Imaging episodic memory: implications for cognitive theories and phenomena

Functional neuroimaging studies are beginning to identify neuroanatomical correlates of various cognitive functions. This paper presents results relevant to several theories and phenomena of episodic memory, including component processes of episodic retrieval, encoding specificity, inhibition, item versus source memory, encoding-retrieval overlap, and the picture-superiority effect. Overall, by revealing specific activation patterns, the results provide support for existing theoretical views and they add some unique information which may be important to consider in future attempts to develop cognitive theories of episodic memory.     

Implicit theories and motivational focus: Desired future versus present reality

People’s beliefs concerning their abilities differ. Incremental theorists believe their abilities (e.g., intelligence) are malleable; entity theorists believe their abilities are fixed (Dweck in Mindset: the new psychology of success. Random House, New York, 2007). On the basis that incremental theorists should emphasize improving their abilities for the future, whereas entity theorists should emphasize demonstrating their abilities in the present reality, we predicted that, when thinking about their wishes, compared to entity theorists, incremental theorists focus more toward the desired future than the present reality. We assessed participants’ motivational focus using a paradigm that differentiated how much they chose to imagine the desired future versus the present reality regarding an important wish (Kappes et al. in Emotion 11: 1206–1222, 2011). We found the predicted effect by manipulating (Study 1) and measuring implicit theories (Study 2), in the academic (Study 1) and in the sport domain (Study 2).     

Implicit theories of relationships: Implications for relationship satisfaction and longevity

The role of implicit theories in romantic relationships was investigated in two studies. People holding a soulmate theory, who believed that finding the right person is most important for a satisfying relationship, were compared to people holding a work–it–out theory, who believed that effort is most important for building a successful relationship. In Study 1, college students (N = 527) completed a set of questionnaires, including measures of relationship theories and functioning within romantic relationships. Approximately 8 months later, a subset of these students (N = 176) completed a second set of questionnaires for Study 1. The implicit theories were highly stable over time (r = .74). For soulmate theorists, feelings that one’s specific partner is ideal predicted relationship satisfaction and relationship longevity to a greater extent than for work–it–out theorists. Whereas Study 1 investigated people’s theories of relationships as ends of a bipolar continuum, a separate study explored people’s theories of relationships as two unipolar dimensions. Findings from Study 2 (N = 266) supported a representation of the theories as two negatively correlated factors, and supported findings from Study 1 highlighting the role of the interaction between the relationship theories and partner fit in predicting relationship satisfaction.     

Implicit theories and IQ test performance: A sequential mediational analysis

The mediational role of worry and practice time in explaining the relationship between implicit theories of ability and performance was examined in two studies. It was hypothesized that holding an implicit theory of ability as fixed and unchangeable would impair test performance. Worry and time invested in practicing prior to taking a test were predicted to mediate the direct effect of implicit theories on performance. These predictions were supported, using both correlational (Study 1) and experimental (Study 2) methods. The results also suggest that entity beliefs lead to decreased practice and performance even when initial failure is not encountered. The theoretical and practical implications of these findings are discussed.     

Children's theories of god: explanations for difficult-to-explain phenomena

Participants in 3 age groups (preschoolers, 3rd graders, and college students) generated explanations for various phenomena. Participants with higher levels of religious involvement provided more attributions to God than participants with lower levels of religious involvement. Also, older participants provided more attributions to God than younger participants. The results suggest that individuals who have higher levels of religious involvement develop theorylike understanding based on their conception of God. It appears that this theorylike understanding has explanatory utility that increases with age.     

Implicit theories about groups and stereotyping: the role of group entitativity

The consequences of holding an entity (i.e., the belief that a group's characteristics are fixed) or incremental (i.e., the belief that a group's characteristics are malleable) implicit theory about groups was examined for stereotyping and perceptions of group entitativity. Two studies showed that implicit theories about groups affect stereotyping by changing perceptions of group entitativity. Study 1 found that entity theorists were more likely to stereotype than incremental theorists and that perception of group entitativity significantly accounted for this relation. In Study 2, implicit theories of groups were manipulated via instruction set and entity theorists stereotyped more and perceived groups as more entitative than incremental theorists. Again, the effect of implicit theory was significantly, although partially, mediated by perceptions of group entitativity. The roles of implicit theories about groups and perceptions of group entitativity are discussed regarding stereotyping.     

Implicit theories of shyness in American and Chinese children

This study examined whether implicit theories of shyness differed between American and Chinese children and how this difference helped explain cultural variations in stereotypical views about shy children and relationship with shy peers. We found that regardless of cultural group, children's implicit theories of shyness were not related to their own shyness, but were associated with stereotypical views about shy children (positively) and relationship with shy peers (negatively). American children reported stronger entity theories of shyness, i.e., they were more likely to view shyness as a stable and immutable trait than Chinese children, which partly explained why they had worse relationships with shy peers. These findings highlight the important roles implicit theories may play in understanding cultural similarities and differences in interpersonal perception and relationship.     

Implicit theories and the evaluation of group process and performance

Previous research has shown that people hold implicit theories or beliefs about relationships between aspects of group process and task accomplishment. These implicit theories, in the presence of evaluative information, affect reports about groups. However, many issues about the impact of implicit theories are unresolved, including whether implicit theories combine differently with positive and negative information and the role of memory in the impact of implicit theories. Two experiments reported here found that (1) implicit theories and negative but not positive information affected people's reports and (2) the operation of implicit theories was unrelated to retrieval processes in memory for facts about an observed group. Implications of the findings for methods of research on groups and for organizational practices involving groups are discussed.     

Implicit theories of relationships: moderators of the link between conflict and commitment

In two studies, implicit theories of relationships were examined as moderators of the association between experienced conflict and commitment. Study 1 involved 128 individuals in heterosexual romantic relationships and employed an event-contingent diary procedure in which disagreements were recorded throughout a 10-day period. Study 2 was conducted in the laboratory and involved 75 heterosexual couples who discussed problems in their relationship, with commitment measured before and after discussion. Multilevel random coefficient models revealed that conflict was generally associated with lower commitment but less so with growth belief. Also, growth belief was most beneficial under negative relationship conditions, such as when one possessed a less favorable view of the partner to begin with and when the issue remained unresolved after discussion.     

Implicit theories of intellectual virtues and vices: A focus on intellectual humility

Psychological science has consistently highlighted links between gratitude and religion, however mediating pathways by which religion relates to gratitude remain ambiguous. Further, it is unclear whether religious gratitude (e.g., gratitude to God) is more related to well-being than general gratitude. To address these gaps, we assessed for both religious and general dimensions of gratitude alongside measures of religious commitment and mental/physical well-being in a diverse sample of n?=?405 adult individuals. Consistent with previous research, gratitude was positively correlated with religious commitment (r?=?0.45, p?<?0.001). This relationship, however, was fully mediated by gratitude towards God. Using hierarchical linear regression, results further found that the interaction of religious commitment and religious gratitude added unique variance in predicting mental well-being, over and above general gratitude. This suggests that being grateful to God enhances the psychological benefits of gratitude in accordance with one's level of religious commitment.     

The shape of self-evaluation: Implicit theories of intelligence and judgments of intellectual ability

Self-report distributions of self-evaluations are proposed to convey information beyond unidimensional (e.g., Likert-type) measures. Two studies tested the hypothesis that the shape of a distribution-type measure of self-evaluation of intellectual ability, as well as the central tendency and variability, is a meaningful indicator of individual differences. Specifically, one correlational study showed that measures of central tendency, variability, and skew were uniquely associated with self-ratings of ability level, self-certainty, and implicit theories of intelligence, respectively. An experiment explored the finding that incremental theorists (Dweck, 1999) reported more negatively skewed distributions than entity theorists. Only incremental theorists who wrote essays about recent intellectual growth created negatively skewed distributions; entity theorists did not. Evidence supports the hypotheses that self-report distributions are multiply informative and idiographic measures of self-evaluation, that negative skew on intellectual ability distributions can represent perceptions of growth, and that incremental theorists typically take this perspective when evaluating their own intellectual ability.     

Implicit theories of emotion: affective and social outcomes across a major life transition

The authors demonstrate that people differ systematically in their implicit theories of emotion: Some view emotions as fixed (entity theorists), whereas others view emotions as more malleable (incremental theorists). Using a longitudinal and multimethod design, the authors show that implicit theories of emotion, as distinct from intelligence, are linked to both emotional and social adjustment during the transition to college. Before entering college, individuals who held entity (vs. incremental) theories of emotion had lower emotion regulation self-efficacy and made less use of cognitive reappraisal (Part 1). Throughout their first academic term, entity theorists of emotion had less favorable emotion experiences and received decreasing social support from their new friends, as evidenced by weekly diaries (Part 2). By the end of freshman year, entity theorists of emotion had lower well-being, greater depressive symptoms, and lower social adjustment as indicated in both self- and peer-reports (Part 3). The emotional, but not the social, outcomes were partially mediated by individual differences in emotion regulation self-efficacy (Part 4). Together, these studies demonstrate that implicit theories of emotion can have important long-term implications for socioemotional functioning.     

Einstein's theory of theories and types of theoretical explanation

In this paper I draw on Einstein's distinction between “principle” and “constructive” theories to isolate two levels of physical theory that can be found in both classical and (special) relativistic physics. I then argue that when we focus on theoretical explanations in physics, i.e. explanations of physical laws, the two leading views on explanation, Salmon's “bottom‐up” view and Kitcher's “top‐down” view, accurately describe theoretical explanations for a given level of theory. I arrive at this conclusion through an analysis of explanations of mass—energy equivalence in special relativity.     

When destiny hurts: Implicit theories of relationships moderate aggressive responses to ostracism

The current research investigates the role of implicit theories of relationships in modulating aggressive responses to ostracism. Three studies tested whether destiny beliefs (that potential relationships are either fundamentally compatible or not) predispose people to behave aggressively in the wake of ostracism. In Study 1, individual differences in destiny beliefs moderated the relationship between ostracism and aggressive affect. Two additional studies showed that manipulated destiny beliefs (vs. growth beliefs) caused ostracized participants to blast a provocateur with aversive noise (Study 2) and to give a destructive job candidate evaluation to a stranger (Study 3). These results highlight the significance of implicit theories in understanding risk factors for ostracism-related aggression.     

Attentive fields: valid scientific constructs or elusive theoretical entities: a reply to Pressey

Pressey conveys the impression that we misunderstood and misapplied his construct of attentive field. In this rejoinder it is argued that by Pressy's own definition and application of this construct his theory should be able to account for our results.     

Implicit theories and context in personal recollection: Romanians' recall of their political and economic past

Ross argued that people employ implicit theories of stability and change as they remember previously held attitudes or prior states of affairs. He acknowledged that the application of these theories is conditional, but does not explore what these conditions might be. We examine here whether implicit theories are context‐sensitive, that is, whether implicit theories that apply when present and past contexts are similar also apply when the present and past contexts differ. The issue is explored by looking at Romanians' memory for previously held political opinions and prior prices for common and uncommon products. The results suggest that memory for prices is sensitive to changes in the political – economic environment, but memory for political opinions is not. Copyright © 2001 John Wiley & Sons, Ltd.     

A multitrait-multimethod validation of the Implicit Association Test: implicit and explicit attitudes are related but distinct constructs

Recent theoretical and methodological innovations suggest a distinction between implicit and explicit evaluations. We applied Campbell and Fiske's (1959) classic multitrait-multimethod design precepts to test the construct validity of implicit attitudes as measured by the Implicit Association Test (IAT). Participants (N = 287) were measured on both self-report and IAT for up to seven attitude domains. Through a sequence of latent-variable structural models, systematic method variance was distinguished from attitude variance, and a correlated two-factors-per-attitude model (implicit and explicit factors) was superior to a single-factor-per-attitude specification. That is, despite sometimes strong relations between implicit and explicit attitude factors, collapsing their indicators into a single attitude factor resulted in relatively inferior model fit. We conclude that these implicit and explicit measures assess related but distinct attitude constructs. This provides a basis for, but does not distinguish between, dual-process and dual-representation theories that account for the distinctions between constructs.
