Better living through generalizability theory: Applications to psychotherapy

Abstract 1: Recent research indicates that only a small portion of supportiveness reflects the objective properties of providers. Instead, supportiveness primarily reflects the unique relationships among specific recipients and providers (i.e., relational effects), thus suggesting new approaches to support interventions. We investigated the possibility that similar relational effects occur for therapy process constructs (e.g., working alliance). Isolating relational effects in psychotherapy requires that each client receive treatment from more than one therapist during the same period of time. Therefore, we conducted analog studies in which therapy clients and students viewed videos of therapists and then rated expected therapist supportiveness and expected therapy process constructs for each therapist. Two studies indicated very strong relational effects in therapist supportiveness and therapy process constructs. In addition, process constructs were correlated strongly with supportiveness (Study 1) and favorable affect (Study 2) for relational effects specifically. Implications for integrating research on perceived support and therapy process were discussed.

Abstract 2 (Time permitting): Identifying the treatments that are most effective for specific clients (i.e., client-treatment matching) is a major goal of research in psychological therapy. Unfortunately, there is little evidence that clients differ in the treatments to which they respond. This could result from the use of between-subjects designs that might be insensitive to client-treatment matching. In other areas of psychology, Generalizability (G) and Social Relations Model (SRM) designs routinely obtain large, conceptually identical matching effects. The current study investigated client-treatment matching using a G/SRM design. Post-partum women with a history of drug use completed three computer-delivered treatment segments of a brief motivational intervention, and rated themselves on state motivation for change following each segment. Strong client-treatment matching effects were found when using G/SRM analyses, but not when using between-subjects analyses. G/SRM methods might be more sensitive to client-treatment matching effects than are commonly used between-subjects designs.

Who is deserving? Religious fundamentalism and just world belief


When individuals observe the outcome of events, they often formulate attributions regarding deservingness based on a match between the valence of the outcome and attributes of the target such as responsibility or blame. Not only do these attributions include aspects of the target's character but are also often based on general worldviews (e.g., "individuals get what they deserve"). One common worldview is that good people are rewarded and bad people are punished; this is the Just World Belief. I propose that one's religious views are an important source in formulating worldviews such that the religion provides a mechanism by which justice is achieved.
In the study i will discuss, we examined the perception of deserved outcomes associated with the belief in a just world (BJW) and religious fundamentalism (RF). Interviews with videotaped targets varied in targets religiosity, responsibility, and outcome valence (good/ bad). Participants either low (LF) or high (HF) on RF, formulated an impression of how deserving a target was for a situational outcome. Participants low in RF held targets to be less deserving of a bad outcome than a good one; the HF group showed this to a lesser degree. HFs believed the target was more deserving of a bad outcome than did LFs, even in conditions in which the target was not responsible for the outcome. Religious fundamentalism is related to attributing greater deservingness of outcomes (i.e., a stronger BJW). October 1 :Joel Quamme

Familiarity-based recognition memory with similar lures: Predicting test format effects with the Complementary Learning Systems (CLS) model.


Some individuals with damage to the hippocampus exhibit impairments in "Yes-No" recognition ("did you see this before?"), but not forced-choice recognition ("which of these did you see?"), when targets must be distinguished from highly similar lures. The Complementary Learning Systems (CLS) model explains this dissociation in that hippocampal damage impairs the ability to recollect specific details about events, but preserves the ability to make discriminations of stimulus familiarity. I will discuss two experiments in which my colleagues and I tested two further predictions of this CLS mechanism in normal healthy participants using picture stimuli with highly similar lures. First, the CLS model predicts relying exclusively on familiarity discriminations should "impair" forced choice recognition when targets are presented with non-corresponding lures (the lures are similar different targets), but not when targets are presented with corresponding lures (the lure and target are similar to each other). Second, the CLS model predicts that discrimination performance on the Yes-No recognition is driven primarily by a "recall-to-reject" strategy were lures are rejected upon recalling their corresponding target. The results supported both predictions. The implications of the results for understanding both normal and impaired episodic recognition are discussed.

Sexual Selection and the Psychological Architecture of Intergroup Bias.

Abstract: Evidence from several studies are utilized to shed light on the evolutionary functions of intergroup bias, as well as the proximal psychological mechanisms motivating its expression. Across several measures of race bias, I show that that race bias emerges solely when the outgroup exemplar is male, not female. These effects are moderated by individual differences in fearfulness among female research subjects, and aggression among male subjects. These effects track conception risk across the menstrual cycle for female participants, and are strongest among women with high self-appraised vulnerability to sexual coercion. These results demonstrate that antipathy toward outgroup targets is modulated by adaptive individual differences in emotional dispositions that vary between men and women, and underscore the importance of considering gender differences in how fear and aggression are utilized as functional responses to threatening outgroup targets.

Biographical Sketch: Carlos David Navarrete is an assistant professor in social psychology at Michigan State University. Born in Southern California, he completed his postdoctoral, graduate, undergraduate, high school, elementary, and kindergarten science training in the area. He holds a Ph.D. in biological anthropology from UCLA, and has completed postdoctoral training in social psychology and psychophysiology at UCLA and at Harvard University. He has conducted fieldwork in rural Costa Rica and in urban Los Angeles, and now conducts laboratory research using physiological measures of anxiety and arousal within artificial virtual environments. His research contacts the nexus of race and gender discrimination as a window to understanding the evolved underpinnings of intergroup bias. Current research employs the use of diverse methods ranging from questionnaires, latency-response measures, psychophysiological measurement, and behavioral observations within immersive, virtual environments ("virtual reality).

Reasons for having children among three generations in the US
Abstract: Empirical work exploring the reasons why people want to have children have been dominated by economic, sociological, and partly anthropological theories. Some of these theories argue that the value-of-children concept (benefits and costs) represents a basis for rational decisions regarding fertility. In this presentation I will talk about the perceived value of children across two generations and the factors that may shape this perception. It was assumed that intergenerational relationships as well as general values affect how people see the reasons for or against having children. Additionally, the predictive power of value of children on fertility preferences and behavior was analyzed for both generations.
Dyads comprising of American adolescents and their mothers (N = 337) participated in this study. Each participant rated the importance of the benefits and costs associated with having children (e.g., affection value, traditional value of children). Regarding the importance of the value of children, mean differences were revealed between the two generations as well as between genders. Hierarchical regression analyses indicated the importance of transmission effects and general values such as individualism, collectivism, and religiosity for the perceived value of children. The value of children was not a strong predictor for fertility preferences and behaviors as expected, but intergenerational transmission of fertility patterns occurred. October 29: Bill Rogers

Difference Scores Reconsidered: Moratorium Lifted?
Abstract: The use of difference scores and pre-post designs have received a steady pummeling in behavioral science over the last four decades. This presentation does not intend a full rehabilitation of difference scores, but rather, demonstrates that proposed alternatives to difference scores suffer under the same psychometric conditions that prompted the banishment of difference scores in the first place. This can be shown in both traditional regression and structural equation modeling approaches to analysis. It is also shown that the inappropriate use of difference scores alternatives can attenuate the detection of effects where a difference function is the true form in the population.

Individual differences in the planning scope of language production: Evidence from eye movements
Abstract: The scope of speakers planning in language production varies in response to external pressures (e.g., time pressure, audience presence). These effects indicate a flexibly incremental production system: Speakers plan utterances piece-by-piece, but external pressures affect the size of the pieces speakers buffer. In the current study, speakers described picture arrays to partners in a matching game. The arrays sometimes required speakers to note a contrast between a sentence-initial object (e.g., a four-legged cat) and a sentence-final object (e.g., a three-legged cat). Based on prior screening, we selected participants who differed on working memory span. Eye movement measures revealed that high-span speakers spent more time fixating the contrasting pictures prior to articulation onset than did low-span speakers. As a result, high-span speakers were also more likely to reference the contrast early in speech. We conclude that working memory plays a substantial role in the flexibility of incremental speech planning.

Vanilla or Mango: Existential Anxiety, Structure, and Novelty Seeking
You are at the ice cream stand. You choose vanilla, while your friend chooses a new mango flavor. You reflect upon your decision and wonder: 1) What was it that made you stick with your old favorite? and 2) What would have led you to try the unfamiliar mango ice-cream instead? There has been a considerable amount of novelty seeking research that has examined the importance of individual differences in exploratory behavior (i.e. Raju, 1980; Steenkamp & Baumgartner, 1992; Wood & Swait, 2000). While this research has identified several important moderators in predicting novelty seeking behavior, a more comprehensive explanation as to why different individuals choose to either avoid or embrace novelty is lacking. Recently, social psychologists have turned to an existential theory of human motivation, terror management theory (TMT; Greenberg, Pyszczynski, & Solomon 1986), in an attempt to understand the motivational underpinnings of why individuals seek or avoid novelty. According to TMT, the existential anxiety that arises from our implicit awareness of our own mortality plays a pivotal role in the extent to which we embrace novelty as a potential source of self-expansion and excitement or eschew it as a potential threat to our existing self-concept and beliefs (Neuberg & Newsom, 1993; Raju, 1980). Recently, TMT research has shown that when mortality is salient, individuals who are high in personal need for structure (PNS; Neuberg & Newsom, 1993) prefer simplistic interpretations of both their material and social world (Landau et al., 2004, Landau et al., 2006, Landau et al., 2008). While this research suggests that both existential motives and individual differences influence our desire to seek or avoid novelty, the extent to which environmental context affects these preferences has not yet been explored. Extending this previous research, we examined whether these effects would generalize outside of a social domain and whether the amount of structure present in the choice context would further moderate the extent to which individuals would avoid or seek novelty. In two studies, mortality (vs. pain) was made salient and participants completed a simulated choice task in which they were asked to select food items from a restaurant menu. The amount of structure in the choice environment was manipulated by changing the organization of menu items. The following results were observed when mortality (vs. pain) was salient. When high PNS individuals perceived less structure in the choice environment, they avoided novelty (Study 1). When low PNS individuals perceived greater structure in the choice environment, they sought novelty (Study 2). These results suggest that high and low PNS individuals engage in different terror management strategies. When mortality is salient, high PNS individuals respond to unstructured choice environments by avoiding novelty. By contrast, low PNS individuals resist structured choice environments by seeking novelty in their choices. This research introduces and tests a theoretical framework that establishes the role of motivational factors in novelty seeking behavior, which to date, has been neglected by past research. Furthermore, the current research builds on previous TMT literature, which has primarily focused on the relationship between heightened concerns about mortality and avoidance of novelty among high PNS individuals but has not explored novelty seeking among low PNS individuals (Landau et al. 2004; Landau et al. 2006; Landau et al. 2008). The present research shows that mortality salience elicits differential terror management processes among both high and low PNS consumers, but also that this relationship is moderated by the amount of structure in the choice environment.

Stress and Relapse: A Role for k Opioids in Stress-Related Behaviors and Drug Seeking During Abstinence

Abstract: Opioids have been characterized in a variety of ways throughout history, ranging from being hailed as miracles of western medicine to being demonized as destructive and addictive substances. The discovery of opioid receptors and endogenous opioid peptides has led to increased insight in the role of this neurochemical system in the regulation of various behaviors and psychiatric disorders. Three subtypes of opioid receptors have been cloned, the m, d and k receptors. At one time ê opioid agonists were proposed as candidate pharmacotherapies for cocaine addiction, mainly due to their ability to decrease dopamine neurotransmission and attenuate behavioral effects of cocaine in laboratory animals. Recent studies, however, suggest that ê agonists also may mimic and/or enhance some of cocaines effects through mechanisms related to stress. The first study used a reinstatement procedure to examine the ability of the êopioid agonists spiradoline and enadoline to reinstate extinguished cocaine seeking in squirrel monkeys previously trained to self-administer cocaine under a second-order schedule of IV drug injection. Opioid- and stress-related mechanisms were evaluated in antagonism studies with the non-selective opioid antagonist naltrexone, the k opioid receptor selective antagonist nor-BNI, the corticotropin-releasing factor receptor antagonist CP 154,526, and the ±2 adrenoceptor agonist clonidine combined with either spiradoline or enadoline. When tested alone, priming with spiradoline and enadoline induced significant reinstatement of cocaine-seeking behavior. Spiradoline- and enadoline-induced reinstatement of drug seeking was attenuated by naltrexone, but not nor-BNI. CP 154,526 and clonidine also antagonized spiradoline-induced reinstatement of cocaine seeking. The results point to potential interactions between activation of a subtype of º opioid receptors and central corticotropin-releasing factor and noradrenergic stress systems in the reinstatement of cocaine seeking, and that the k opioid system likely regulates stress-induced behavior following abstinence from drugs of abuse. More so than in other abused drugs, stress and anxiety play a highly prominent role in alcohol relapse, as abstinent alcoholics report feelings of anxiety as one of the main reasons for relapsing following treatment. The next study sought to examine the regulation of the behavioral stress response via k opioid mechanisms following withdrawal from alcohol. Rats were given access to an ethanol or control liquid diet for 28 days and following removal of the diet, rats received injections of nor-BNI or saline. Exploratory behavior in the elevated plus maze was then examined at least 24 hours following pretreatment and removal of the diet. Rats maintained under the ethanol liquid diet condition showed a significant decrease in the percentage of time spent exploring the open arms, an indication of a heightened anxiety-like state, compared to those receiving the control diet. nor-BNI reversed this effect, as rats injected with a 20 mg/kg dose displayed levels of open arm exploration comparable to that of controls without affecting motor behavior. These data indicate that kappa opioid mechanisms play a role in the regulation of stress-related behavior due to withdrawal from ethanol. Taken together the results of these studies suggest that decreasing k opioid activity in the brain may provide a useful therapeutic approach for decreasing stress-related behaviors associated with abstinence, including relapse.

Association Between Parents and Peers in Adolescence

Abstract: The family and the peer group are important developmental contexts in adolescence, which are interconnected. The presentation summarizes evidence from a German longitudinal study on divorced and nuclear families on the association between (1) profiles of family (dys)functioning (such as parenting, family climate, and triangulation) and (2) interparental conflict and peer relationships. The perspective is
extended toward a cross-cultural perspective, comparing German and Chinese nuclear families.

The role of Prosody in Silent Reading

Abstract: Prosody is found in all spoken languages. The implicit prosody hypothesis (Fodor, 2002) contends that silent readers have a prosodic inner voice, although this role is largely uninvestigated. To avoid interpretative ambiguities associated with speech production tasks, we have utilized a silent reading task in two experiments to investigate prosody in written English. Participants read short paragraphs, in which select words were capitalized. Per a cover story, some instances of capitalization were intentional, a new technique to enhance the reading experience. In contrast, other instances of capitalization were the result of a computer virus. Participants judged (on a 5-point scale) the helpfulness of capped words, under the ruse of helping an editor sort this mess out. As hypothesized, participants rated the capped words as more helpful, only when these target words were new (i.e., prosodically-focused) rather than given, consistent with Selkirks (1995) Theory of Focus Projection. Experiment 3, to be launched moments after todays talk, will extend our investigations to 1) function words and 2) response latencies.

Forecasting Relational Supportive Matching

Abstract: Perceived support is important because of its link to mental and physical health. Although an important goal of social support research has always been to guide the development of interventions, the effectiveness of these interventions has been disappointing. Perceived support is composed of a blend of recipient personality, the objectively-supportive properties of providers, and the unique relationships between specific recipients and providers. Although most social support interventions have focused on provider influences, unique relationships are the strongest influences on perceived support. Harnessing relational influences in intervention requires that a) the relational influences on perceived support are
linked to mental health and b) it is possible to forecast the development of uniquely supportive relationships between specific recipients and providers. Recent research on these requirements will be presented.

The influence of Beliefs on Comprehension

Abstract: I will describe a new line of research that is designed to assess what (if any) influence beliefs about a topic might have on the way readers comprehend and remember information that is either consistent or inconsistent with what they believe. In particular, I am interested in whether beliefs impose constraints on comprehension, or whether readers can successfully adjust comprehension processes to focus on consistent or inconsistent information based on their goals. I will outline the basic research approach, and present data from two experiments in which subjects who were either believers or disbelievers in evolution comprehended evidence that supported or refuted evolution.

Socialization of Anger and Shame: Cultural Variations in a Collectivist Context

Abstract: Cultural comparisons allow us to examine both universal and culturally variable aspects of emotional development. Our research in Nepal has allowed us to detect subtle differences between two distinct ethnic groups  the Tamang and the Brahmans  that are similar in many ways. School age children differ in these groups differ in their beliefs about how they would feel in challenging situations as well as why they feel those ways and whether they wish to reveal their feelings. Their beliefs are consistent with our observations of ethnic group differences in caregiver responses to child anger and shame, which in turn are consistent with group differences in elders criteria for competence in children. The findings are discussed in terms of the critical need to understand why such differences exist.

The Vigil of Selfishness: Stalling Utility in Fixed-Resource Mixed-Sum Game Theory

Abstract: Stalling may be defined as deliberate inaction intended to reduce the utility of an opposing strategy (active), or increase the utility of a future strategy (passive). In either form, it is evident in sporting games, negotiation, and even human courtship. In my approach, a stall point is formulated as a stochastic transition between two Nash equilibria. Results of an experiment involving genetic algorithm supports genotypic optimality of a active stalling strategy in a mixed sum game, as well as the stability of the stall point itself. A study investigating passive stalling is discussed, along with applications to job and mate selection. Finally, the findings in total are compared to an archival data set of over 4.8 million human behaviors.

Sex, sports, & testosterone: New approaches for exploring gender differences in competition Sex differences in competitiveness and related attributes are well established. However, the extent to which such differences originate from social conditions or evolved predispositions remains fiercely debated. To address this issue, I have shown that population-level analyses of relative sports performance can estimate sex differences in competitiveness. Furthermore, I have demonstrated (1) a robust sex difference in running, with proportionally 2-4 times more males running relatively fast in all U.S. populations and that (2) this difference has not diminished since the mid-1980s, despite greatly increased athletic opportunities for females. Here I show that the sex difference in relative performance for U.S. swimmers was substantial in the 1970s but has now disappeared. The strikingly different patterns in swimming and running imply that, although sex differences in competitiveness may indicate evolved predispositions, they also reflect social and developmental factors. After presenting these results, I will briefly describe new experiments designed to identify hormonal correlates of competitiveness.
