How need for cognition affects the formation of performance expectancies at school

Individuals with low Need for Cognition (NFC) have been found to process information using a peripheral route compared to individuals higher in NFC. These differences affect the formation of performance expectancies. Based on previous work demonstrating that the formation of performance expectancies can be understood as an information processing event and that inferring expectancies from the specific self-concept requires cognitive motivation, we tested whether students with higher NFC had performance expectancies in a specific subject that more strongly depended on specific self-concept. The participants (554 tenth grade students) reported their NFC, performance expectancies, general self-concept, and specific self-concepts in mathematics and English. Actual performance was assessed for mathematics. Multiple linear regressions supported the interaction-hypothesis concerning performance expectancies in mathematics and English. In addition, the higher the students’ NFC, the stronger actual performance in mathematics related to the specific self-concept. The results suggested that performance expectancies mediated the effect of self-concept on performance. NFC is an important variable influencing motivational processes, and should be included in models describing the relation between self-concepts and individuals beliefs or behaviors.     

Do anxious parents interpretive biases towards threat extend into their child's environment?

Anxiety disorders are known to run in families [Turner, S. M., Beidel, D. C., & Costello, A. (1987). Psychopathology in the offspring of anxiety disorder patients. Journal of Consulting and Clinical Psychology, 55(2), 229–235] and environmental factors may largely account for the concordance between parental and child anxieties. Cognitive psychology models emphasise the importance of interpretive biases towards threat in the maintenance of anxiety and it is well established that anxious adults and children display similar interpretive biases and that these biases in anxious parents and their children are correlated. This raises the question of whether anxious cognitions/cognitive style may be transmitted from parent to child. We propose that this is more likely if anxious parents demonstrate interpretive biases not only about potential threats in their own environment but also about potential threats in their child's environment. Forty parents completed a recognition memory measure of interpretation bias adapted from Eysenck, Mogg, May, Richards, and Mathews (1991) [Bias in interpretation of ambiguous sentences related to threat in anxiety. Journal of Abnormal Psychology, 100(2), 144–150] to measure biases in response to potentially threat provoking situations involving themselves and their child. The interpretive biases demonstrated by parents were similar across situations involving themselves and their children. As expected, parental interpretive biases were further modified by anxiety with higher levels of parental anxiety associated with more negative interpretive biases about situations in their own and their child's environment, although this association was significantly stronger for potentially threat provoking situations in their own environment. These results are consistent with parent's interpretive biases extending beyond their own environment into their child's environment, although future research should continue to consider the mechanisms by which anxious parents may transmit fear cognitions to their children.     

What can we learn from toddlers about categorical perception of color? Comments on Goldstein, Davidoff, and Roberson

We comment on Goldstein, Davidoff, and Roberson’s replication and extension (Journal of Experimental Child Psychology, 102, 219-238 [2009]) of our study of the effect of toddlers’ color term knowledge on their categorical perception (CP) of color (Journal of Experimental Child Psychology, 90, 114-141 [2005]). First, we discuss how best to assess color term knowledge when concerned with the effects of language on color CP. A reanalysis of our data indicates that even toddlers who do not know the terms for the relevant focal colors still show CP. Second, we comment on Goldstein and colleagues’ finding of blue-purple CP, as we did, but not of blue-green CP in Himba toddlers. We present contrasting data from Wright (unpublished PhD thesis, University of Surrey, 2006) that demonstrates blue-green CP in Himba toddlers. Finally, we discuss the limitations of the approach taken by all of these investigations and discuss theoretical accounts of the origin and nature of color CP.     

Brain mechanisms associated with background monitoring of the environment for potentially significant sensory events

Background monitoring is a necessary prerequisite to detect unexpected changes in the environment, while being involved in a primary task. Here, we used fMRI to investigate the neural mechanisms that underlie adaptive goal-directed behavior in a cued task switching paradigm during real response conflict or, more generally, when expectations on the repetitive features of the environment were violated. Unexpected changes in sensory stimulus attributes in the currently unattended stimulus dimension thereby led to activations in a bilateral network comprising inferior lateral frontal, intraparietal, and posterior medial frontal brain regions, independent of whether these attributes elicited a factual response conflict or not. This fronto-parietal network may thus play an important role in adaptive responding to potentially significant events outside the current focus of attention.     

Empathy and emotion recognition in semantic dementia: A case report

Recent studies have demonstrated that patients suffering from frontotemporal lobar degeneration (FTLD) show impairments in empathy and emotional processing. In this study, we examined two different aspects of these abilities in a patient with semantic dementia (SD), a variant of FTLD. The first aspect was the assessment of the cognitive and emotional components of empathy through the Interpersonal Reactivity Index. The second was the naming and comprehension of emotions using the Ekman 60 Faces Test. The patient’s emotion word knowledge was spared and the emotional aspects of empathy preserved. Conversely, the patient performed below average for all of the basic emotions when an emotion word had to be matched with a picture. When picture-to-picture matching was tested, however, the patient was able to recognize happiness. This case is a good example of a dissociation of covert and overt emotional functioning in SD. Results are discussed in terms of the impaired empathic behavior and emotional functioning in FTLD.     

Individual differences in conflict-monitoring: testing means and covariance hypothesis about the Simon and the Eriksen Flanker task

Conflict and context slow-down have been proposed as indicators of a conflict-monitoring system that initiates cognitive control to resolve conflicts in information processing. We investigated individual differences in conflict-monitoring and their associations with working memory (WM) and impulsivity. A total of 150 adults completed a Simon and an Eriksen flanker task, together with measures of WM and impulsivity. On both tasks, responses were slower and less accurate on incompatible than on compatible trials (conflict effect), and the conflict effect was larger when the preceding trial was compatible than when it was incompatible (context effect). Stimulus repetition did not explain the context effect. Individual differences could be attributed to three separable factors for each task: general speeded performance, conflict effect, and context effect. Evidence for across-task generality of these factors was sparse. Associations of these factors with impulsivity were weak at best. WM was correlated with general speed, and also with some but not all factors reflecting conflict-related processes.     

Gender and developmental patterns of affect, belief, and behavior in simulated injury events

This study examined the hypothesis drawn from epidemiological data that beliefs and affective reactions of male second, fifth, and eighth graders, undergraduates, and adults in response to a series of four simulated bicycle collisions would show decreased expectation and avoidance of injury in comparison to females. This study also contrasted two additional hypotheses, one suggesting an invincibility belief in teenagers, producing a curvilinear age trend, with risky cognitions increasing from second grade, peaking at eighth grade, and then decreasing in adulthood. The other hypothesis suggested that with exposure, risky beliefs increased linearly, due to desensitization to cues of risk. As predicted, female participants did expect more fear and pain, and less exhilaration, and braked sooner after seeing the hazard than male participants. Linear rather than curvilinear age patterns emerged across films, revealing that the youngest participants anticipated more fear and less exhilaration than older participants. These results parallel developmental trends in which females and younger participants who anticipate more serious consequences are at lower risk for bicycle injury than are males, older children, and adolescents. Limitations of this analogue study and potential questions for both future research and the application of injury prevention techniques are explored.
