Cognitive tendencies of focusing on positive and negative information

We hypothesized individual differences in the tendency to attend to, think about, and focus on positive (or negative) information. A scale measuring these individual differences was constructed and its validity and reliability were examined in three studies. Attention to positive information was related to positive affectivity, extraversion, BAS, optimism. Attention to negative information was related to negative affectivity, neuroticism, BIS, and optimism (inversely). Validity was partially confirmed by a person perception task: individuals high in attention to positive information perceived the character in a story as happy. Attention to positive information was a partial mediator of the relation between extraversion and positive affect and attention to negative information was a partial mediator of the relation between neuroticism and negative affect.     

Producing either positive or negative tendencies to a stimulus associated with shock

A technique is described in which rats are pretrained with reinforcement to bar press. Each bar press was associated with a tone. This tone was later paired with one of two aspects of an electric shock, either at the onset or at the end of the shock, in a situation in which the shock is inescapable. These animals were retested in the operant situation under conditions of extinction, but with tone present as a conditioned reinforcer. The finding was that animals for which the tone was associated with shock onset extinguished quickly, whereas animals for which the tone was paired with shock termination extinguished more slowly.     

Implicit attitude generalization occurs immediately; explicit attitude generalization takes time

People are able to explicitly resist using knowledge about one person to evaluate another person from the same group. After learning about positive and negative behaviors performed by one individual from each of two different groups, participants were introduced briefly to new individuals from the groups. Implicit evaluations of the original individuals readily generalized to the new individuals; explicitly, participants resisted such generalization. Days later, both implicit and explicit evaluations of the original individuals generalized to the new individuals. The results suggest that associative links (e.g., shared group membership) are sufficient for implicit attitude generalization, but deliberative logic (e.g., individual group members are not necessarily the same) can reduce explicit generalization by association. When knowledge distinguishing who did what is unavailable, such as after forgetting, associative knowledge provides the basis of explicit evaluation. We conclude that a simple association linking one individual to another can produce implicit attitude generalization immediately and explicit attitude generalization eventually.     

Ambivalence,prejudice and negative behavioural tendencies towards out-groups: The moderating role of attitude basis

Two experiments explored the relations between prejudice (suppression), (cognitive) ambivalence and negative behavioural tendencies towards out-groups. The current work argues that expressing out-group ambivalence based on cognitive, but not affective, information is a strategy to justify one's otherwise suppressed prejudice, which may ultimately “cover” the discriminatory nature of out-group-directed negative behavioural tendencies. Two experiments show that (1) participants evaluating the out-group in a normative context inducing prejudice suppression are more likely to self-report ambivalent beliefs rather than ambivalent emotions concerning the out-group as compared with participants whose prejudice expression is induced and (2) high-prejudice participants compared with low-prejudice participants are more prone to out-group-directed negative behavioural tendencies when these latter are self-reported after the expression of ambivalent beliefs but not ambivalent emotions concerning the out-group, and when the expression of their prejudicial evaluations is salient but not when it is not. In light of the extent to which ambivalent attitudes towards out-groups are often seamlessly integrated into public discourse, the implications of the findings are discussed not only for intergroup research but also at the societal level.     

Dual identities in intergroup contact: Group status and size moderate the generalization of positive attitude change

To explore the effects of various categorization strategies on intergroup bias within and beyond a contact situation, two experiments were conducted involving groups of different size and/or status that worked together on a cooperative task. Three categorization strategies (decategorization, recategorization, and dual identity) were compared, and bias was measured through symbolic reward allocations to people who were and were not actually encountered. In Experiment 1 (N = 129), we varied group size (minority or majority) and found that it affected bias within the contact situation—minority groups were more biased than majority groups. All of the categorization strategies limited bias and they did so equally well. Outside the contact situation, however, only the recategorization and dual identity strategies limited bias. In Experiment 2 (N = 156), we varied both group status (low or high) and group size. Both of these variables affected bias within the contact situation—high status groups were more biased than low status groups, and minority groups were again more biased than majority groups. Once again, all three categorization strategies limited bias and they did so equally well. Outside the contact situation, however, an interaction among the independent variables was observed. For minority groups, only the dual identity strategy limited bias, but none of the categorization strategies limited bias for majority groups.     

Connectionist simulation of attitude learning: asymmetries in the acquisition of positive and negative evaluations

Connectionist computer simulation was employed to explore the notion that, if attitudes guide approach and avoidance behaviors, false negative beliefs are likely to remain uncorrected for longer than false positive beliefs. In Study 1, the authors trained a three-layer neural network to discriminate "good" and "bad" inputs distributed across a two-dimensional space. "Full feedback" training, whereby connection weights were modified to reduce error after every trial, resulted in perfect discrimination. "Contingent feedback," whereby connection weights were only updated following outputs representing approach behavior, led to several false negative errors (good inputs misclassified as bad). In Study 2, the network was redesigned to distinguish a system for learning evaluations from a mechanism for selecting actions. Biasing action selection toward approach eliminated the asymmetry between learning of good and bad inputs under contingent feedback. Implications for various attitudinal phenomena and biases in social cognition are discussed.     

On the generalization of attitude accessibility after repeated attitude expression

The more accessible an attitude is, the stronger is its influence on information processing and behavior. Accessibility can be increased through attitude rehearsal, but it remains unknown whether attitude rehearsal also affects the accessibility of related attitudes. To investigate this hypothesis, participants in an experimental condition repeatedly expressed their attitudes towards exemplars of several semantic categories during an evaluative categorization task. Participants in a control condition performed a non‐evaluative task with the same exemplars and evaluated unrelated attitude objects. After a 30‐minute interval, participants in the experimental condition were faster than controls to evaluate not only the original exemplars but also novel exemplars of the same categories. This finding suggests that the effect of attitude rehearsal on accessibility generalizes to attitudes towards untrained but semantically related attitude objects. © 2016 The Authors.

Self-ratings of positive and negative affect and retrieval of positive and negative affect memories

Abstract

Based on analysis of self-ratings of mood, positive affect (PA) and negative affect (NA) have been proposed as basic, orthogonal mood dimensions (Watson & Tellegen, 1985). The present study asked subjects (N = 61) to not only provide self-ratings of PA and NA terms but also to retrieve personal memories associated with those terms. Self-rated PA was associated with latency to retrieve PA- but not NA-related memories; self-rated NA was associated with latency to retrieve NA- but not PA-related memories. Self-ratings of PA and NA were not significantly correlated, nor were retrieval latencies for PA and NA memories. Individual item correlations also revealed a strong direct relationship between self-ratings and retrieval latency. The dissociations involving a non-self report measure strengthen the distinction between PA and NA, and the individual item correlations are interpreted as showing that self-ratings of affect are based upon the ease of retrieval of personal memories.     

Strength in positive and negative political attitudes

The aim of the study was to examine whether positive-negative asymmetry can be found in the strength of political attitudes. Two hundred and eleven subjects participated in the study. Attitudes toward political parties were examined by means of a questionnaire with three strength measures. As was expected, attitude intensity, centrality and behaviour were found to be linked together in positive attitudes but not in negative attitudes.     

The eyes have it: making positive expressions more positive and negative expressions more negative

Facial expressions frequently involve multiple individual facial actions. How do facial actions combine to create emotionally meaningful expressions? Infants produce positive and negative facial expressions at a range of intensities. It may be that a given facial action can index the intensity of both positive (smiles) and negative (cry-face) expressions. Objective, automated measurements of facial action intensity were paired with continuous ratings of emotional valence to investigate this possibility. Degree of eye constriction (the Duchenne marker) and mouth opening were each uniquely associated with smile intensity and, independently, with cry-face intensity. In addition, degree of eye constriction and mouth opening were each unique predictors of emotion valence ratings. Eye constriction and mouth opening index the intensity of both positive and negative infant facial expressions, suggesting parsimony in the early communication of emotion.     

Varieties of positive and negative priming

Numerous recent investigations have focused on a particular relation between the roles a stimulus plays in successive displays: when a stimulus ignored by a subject on one occasion is to be attended on a succeeding occasion, reaction time to that stimulus is slowed relative to a control condition. But this is but one possible case ofnegative priming. There are other ways in which negative priming might occur, and there are several varieties of positive priming as well. All these possibilities were explored in the present experiment.     

Individual differences in positive and negative interpretive biases

Student subjects were given the task of writing down the spellings of a series of words (many of them homophones) presented auditorily. Some of the homophones had a negative and neutral interpretation, whereas others had a positive and neutral interpretation. Subjects low in trait anxiety (high extraversion, low neuroticism) produced more positive homophone interpretations than did those low in positive affectivity; this constitutes a positive interpretive bias. Subjects very high in negative affectivity (in terms of trait anxiety) produced more negative homophone interpretations than did those lower in trait anxiety; this constitutes a negative interpretive bias. Theoretical implications of these biases were discussed.     

Comparing positive and negative patterning in human learning

In human causal learning, positive patterning (PP) and negative patterning (NP) discriminations are often acquired at roughly the same rate, whereas PP is learned faster than NP in most experiments with nonhuman animals. One likely reason for this discrepancy is that most causal learning scenarios encourage participants to treat the presentation and omission of the relevant outcome as two events of comparable significance and likelihood. To investigate this, the current experiments compared PP and NP using a predictive learning paradigm based on a mock gambling task. In Experiment 1, one outcome (winning) was made more salient by being less frequent than the alternative outcome (losing). Under these circumstances, PP was learned faster than NP. In Experiment 2, subjects learned two PP and two NP discriminations, one involved win versus no change outcomes, the other involved lose versus no change outcomes. The subjects learned PP faster than NP, but only when discriminating win from no change. We argue that a difference in difficulty between PP and NP relies on a difference in the salience of the outcomes, consistent with the predictions of a relatively simple model of associative learning.     

Measuring dynamic bipolarity in positive and negative activation

The dynamic bipolarity of the positive and negative affective activation, measured with the PANAS scales, was studied using a pre-post design with an intervening experiment. The correlations between (a) the initial positive and negative constructs and (b) the respective change scores were estimated, random and systematic error being removed owing to a convenient structural equation modeling technique. Results demonstrated that a moderate perturbation may induce a medium correlation between latent change scores. Both strict dynamic independence and bipolarity were rejected. This result highlights the importance of individual differences in the way people perceive their affective changes. It is concluded that the PANAS two-factor model of affect provides only an approximate view of the structure and dynamics of mood.
