Knowing Good From Bad: The Paradox of Neuroticism, Negative Affect, and Evaluative Processing.

There are pragmatic benefits to trait-consistent mood states, especially when people are evaluating new objects within the environment (M. Tamir, M. D. Robinson, & G. L. Clore, 2002). The present studies, involving both naturally occurring (Studies 1 and 2) and manipulated (Study 3) mood states, demonstrated such trait-consistent interactions within the context of neuroticism and negative mood states. Individuals high in neuroticism were faster to make evaluations when in a negative mood state like sadness. By contrast, individuals low in neuroticism were faster to make evaluations when in a neutral mood state. The present studies demonstrate that although negative mood states are hedonically unpleasant, they can be beneficial in some ways for individuals high in neuroticism.

The Relative Importance of Three Domains of Positive and Negative Social Exchanges: A Longitudinal Model With Comparable Measures.

Researchers have expressed considerable interest in the question of whether positive or negative social exchanges more strongly affect psychological health, but previous studies have been limited by using nonparallel measures of positive and negative social exchanges, by measuring negative affect only, and by relying largely on cross-sectional designs. The independent effects of positive and negative exchanges on both positive and negative affect were examined in a short-term longitudinal study of 277 older adults, using social exchange measures with parallel content and equivalent reliability and validity. In cross-sectional analyses, positive exchanges predicted positive affect, and negative exchanges predicted negative affect. In longitudinal analyses, however, negative exchanges predicted both positive and negative affect, whereas positive exchanges were unrelated to either outcome. The more potent and longer-lasting effects of negative exchanges have important implications for theory and interventions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"Ten years of research on the false-consensus effect: An empirical and theoretical review": Correction to Marks and Miller.

Reports an error in "Ten years of research on the false-consensus effect: An empirical and theoretical review" by Gary Marks and Norman Miller (Psychological Bulletin, 1987[Jul], Vol 102[1], 72-90). The block quotation on page 73 should be attributed to Crocker (1981). The two sentences immediately preceding this quotation should read: "Friendship groups typically exhibit a high degree of internal similarity with respect to members' beliefs, attitudes, values, and interests. Crocker (1981) reported the following:". (The following abstract of the original article appeared in record 1987-31255-001.) Ten years of research on the false-consensus effect (Ross, Greene, & House, 1977) and related biases in social perception (e.g., assumed similarity and overestimation of consensus) are examined in the light of four general theoretical perspectives: (a) selective exposure and cognitive availability, (b) salience and focus of attention, (c) logical information processing, and (d) motivational processes. The findings indicate that these biases are influenced by a host of variables and that no single explanation can account for the range of data. Instead, each theoretical perspective appears to have its own domain of application, albeit with some degree of overlap into other domains. The data further suggest that two or more specific mechanisms may operate simultaneously or in concert to produce assumed similarity and false-consensus effects. Discussion focuses on identifying the process or sets of processes operating in specific situations. We identify several gaps in the knowledge of mediating relationships and suggest directions for future research. We also discuss issues related to definition and measurement.

A formal cognitive model of the go/no-go discrimination task: Evaluation and implications.

This article proposes and tests a formal cognitive model for the go/no-go discrimination task. In this task, the performer chooses whether to respond to stimuli and receives rewards for responding to certain stimuli and punishments for responding to others. Three cognitive models were evaluated on the basis of data from a longitudinal study involving 400 adolescents. The results show that a cue-dependent model presupposing that participants can differentiate between cues was the most accurate and parsimonious. This model has 3 parameters denoting the relative impact of rewards and punishments on evaluations, the rate that contingent payoffs are learned, and the consistency between learning and responding. Commission errors were associated with increased attention to rewards; omission errors were associated with increased attention to punishments. Both error types were associated with low choice consistency. The parameters were also shown to have external validity: Attention to rewards was associated with externalizing behavior problems on the Achenbach scale, and choice consistency was associated with low Welsh anxiety. The present model can thus potentially improve the sensitivity of the task to differences between clinical populations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Environmental Dependence of Behavioral Control Mechanisms: Effects of Alcohol and Information Processing Demands.

Studies show that alcohol increases a drinker's reliance on the environmental context for the maintenance of inhibitory and activational responding. The author of the present study examined additive effects of alcohol and cognitive load on the cue dependency of inhibitory and activational mechanisms of control. Adults received 0.0 g/kg, 0.45 g/kg, and 0.65 g/kg alcohol and performed a cued go/no-go task that presented simple and complex go and no-go stimuli. Results showed that cue dependency of response inhibition increased as a function of dose, and this effect was similar across low and high cognitive load conditions. These findings are consistent with a capacity limitation account of alcohol impairment that could involve central or output stages of information processing.

Cognitive Processing of Emotional Information in Depression, Panic, and Somatoform Disorder.

Emotional Stroop tasks (subliminal/supraliminal exposures), implicit memory tasks (tachistoscopic word identification), and explicit memory tasks (free recall after incidental learning) with 4 word types (physical threat, positive, negative, and neutral words) were administered to patients with major depressive disorder (n = 30), panic disorder (n = 33), somatoform disorder (n = 25), and healthy control participants (n = 33). On the Stroop task, panic patients showed subliminal interferences for physical threat and negative words, depressive patients showed supraliminal interferences for negative words, and somatoform patients showed supraliminal interferences for physical threat words. No patient groups demonstrated implicit memory biases. On the explicit memory task, depressive and panic patients showed memory biases for negative words; somatoform patients showed biases for physical threat words.

The Interpersonal Effects of Emotions in Negotiations: A Motivated Information Processing Approach.

Three experiments tested a motivated information processing account of the interpersonal effects of anger and happiness in negotiations. In Experiment 1, participants received information about the opponent's emotion (anger, happiness, or none) in a computer-mediated negotiation. As predicted, they conceded more to an angry opponent than to a happy one (controls falling in between), but only when they had a low (rather than a high) need for cognitive closure. Experiment 2 similarly showed that participants were only affected by the other's emotion under low rather than high time pressure, because time pressure reduced their degree of information processing. Finally, Experiment 3 showed that negotiators were only influenced by their opponent's emotion if they had low (rather than high) power. These results support the motivated information processing model by showing that negotiators are only affected by their opponent's emotions if they are motivated to consider them.

A twin study of cognitive function in chronic fatigue syndrome: The effects of sudden illness onset.

Variable reports of neuropsychological deficits in individuals with chronic fatigue syndrome (CFS) may, in part, be attributable to methodological limitations. In this study, these limitations were addressed by controlling for genetic and environmental influences and by assessing the effects of comorbid depression and mode of illness onset. Specifically, the researchers conducted a co-twin control study of 22 pairs of monozygotic twins, in which 1 twin met strict criteria for CFS and the co-twin was healthy. Twins underwent a structured psychiatric interview and comprehensive neuropsychological assessment evaluating 6 cognitive domains. Results indicated that twin groups had similar intellectual and visual memory functioning, but fatigued twins exhibited decreases in motor functions (p = .05), speed of information processing (p = .02), verbal memory (p = .02), and executive functioning (p = .01). Major depression did not affect neuropsychological functioning among fatigued twins, although twins with sudden illness onset demonstrated slowed information processing compared with those with gradual onset (p = .01). Sudden onset CFS was associated with reduced speed of information processing. If confirmed, these findings suggest the need to distinguish illness onset in future CFS studies and may have implications for treatment, cognitive rehabilitation, and disability determination.

Review of Intellectual development: Birth to adulthood.

Reviews the book, Intellectual development: Birth to adulthood by Robbie Case (1985). One method for making tractable the complexities of human cognitive growth is to impose organization via a bold and expansive theory. Piaget's theory is exemplary. Robbie Case, in Intellectual Development: Birth to Adulthood, has improved and extended the approach. In Case's work, stages of cognitive development are revealed by the integration of structural and process analyses. Structural analysis is the use of a formalism or interpretive grid to describe the organization of intellectual operations required by a task. The formalism is Case's theory is the executive control structure, consisting of three lists: a representation of the problem situation, a representation of desired objectives, and cognitive and behavioural strategies. The process analysis provides an account of the integration of executive control structures and information processing capacities that are unique to each of four stages from birth to adulthood. The book succeeds as macrotheory. The issues that must be addressed by a complete account of human cognitive development are clearly summarized. Throughout the book there is considered review of advances in cognitive developmental inquiry. Workable tenets are borrowed, inadequacies are highlighted, and alternatives are put forward. There is a deliberate resolve to repair and continue to build stage theory. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Violations of Implicit Theories and the Sense of Prediction and Control: Implications for Motivated Person Perception.

Beginning with the assumption that implicit theories of personality are crucial tools for understanding social behavior, the authors tested the hypothesis that perceivers would process person information that violated their predominant theory in a biased manner. Using an attentional probe paradigm (Experiment 1) and a recognition memory paradigm (Experiment 2), the authors presented entity theorists (who believe that human attributes are fixed) and incremental theorists (who believe that human attributes are malleable) with stereotype-relevant information about a target person that supported or violated their respective theory. Both groups of participants showed evidence of motivated, selective processing only with respect to theory-violating information. In Experiment 3, the authors found that after exposure to theory-violating information, participants felt greater anxiety and worked harder to reestablish their sense of prediction and control mastery. The authors discuss the epistemic functions of implicit theories of personality and the impact of violated assumptions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
