Social marking,socio-cognitive conflict and cognitive development

This study is concerned with assessing whether social marking, i.e. the correspondence between the cognitive solution of a task and the social relation expressed in the material, is a mechanism of cognitive progress which depends on specific forms of socio-cognitive conflict or on presence of familiar social relations in the material. In the first experiment 5-6-year-old non-conserver children were selected during a pre-test that comprised three spatial transformation tasks. During the test phase, 56 children worked on spatial transformation tasks with an adult partner in four socially marked conditions in which the correctness of the adult model varied. All subjects were individually post-tested on the same tasks with unmarked content. Results showed that, under the same marked conditions in the test phase, more progress took place, at the post-test phase, when subjects had interacted with an incorrect adult model than when they had interacted with a correct one. In the second experiment the hypothesis of an interaction between the nature of the material and the kind of social interaction was examined by means of a factorial design in which the factors were adult versus child partner and marked versus unmarked material. The procedures in the pre- and post-test phase were carried out in the same way as in Experiment I. In the test phase 61 non-conserver children interacted with partners who presented completely incorrect model. The results of post-test phase indicated that there was a main effect of social marking although findings of a condition in which children interact with another child on unmarked material also have shown a certain amount of progress. The findings are discussed with respect to the psycho-social model of cognitive development.     

Context, not conflict, drives cognitive control

Theories of cognitive control generally assume that perceived conflict acts as a signal to engage inhibitory mechanisms that suppress subsequent conflicting information. Crucially, an absence of conflict is not regarded as being a relevant signal for cognitive control. Using a cueing, a priming, and a Simon task, we provide evidence that conflict does not have this unique signal status: Encountering a conflict does not lead to behavioral adjustments on subsequent conflict trials, whereas encountering a nonconflict trial does lead to behavioral adjustments on subsequent nonconflict trials. We propose that this apparent role-reversal can be explained by a mechanism that responds to both the presence and the absence of conflict, down-regulating the visuomotor system following conflict, and up-regulating it following nonconflict.     

Cultural influences on cognitive representations of conflict: interpretations of conflict episodes in the United States and Japan.

This article integrates theory from the cognitive tradition in negotiation with theory on culture and examines cultural influences on cognitive representations of conflict. The authors predicted that although there may be universal (etic) dimensions of conflict construals, there also may be culture-specific (emic) representations of conflict in the United States and Japan. Results of multidimensional scaling analyses of U.S. and Japanese conflict episodes supported this view. Japanese and Americans construed conflicts through a compromise versus win frame (R. L. Pinkley, 1990), providing evidence of a universal dimension of conflict construal. As the authors predicted, Japanese perceived conflicts to be more compromise-focused, as compared with Americans. There were also unique dimensions of construal among Americans and Japanese (infringements to self and giri violations, respectively), suggesting that identical conflict episodes are perceived differently across cultures.     

Post-conflict slowing: cognitive adaptation after conflict processing

The aftereffects of error and conflict (i.e., stimulus or response incongruency) have been extensively studied in the cognitive control literature. Each has been characterized by its own behavioral signature on the following trial. Conflict leads to a reduced congruency effect (Gratton effect), whereas an error leads to increased response time (post-error slowing). The reason for this dissociation has remained unclear. Here, we show that post-conflict slowing is not typically observed because it is masked by the processing of the irrelevant stimulus dimension. We demonstrate that post-conflict slowing does occur when tested in pure trials where helpful or detrimental impacts from irrelevant stimulus dimensions are removed (i.e., univalent stimuli).     

Pharmacological cognitive enhancers: comment on Smith and Farah (2011)

Smith and Farah (2011) provided a thought-provoking and perhaps deliberately provocative literature review of the use of stimulants to improve cognitive functioning in humans. They addressed the apparently increasing willingness of individuals mostly in the United States to use stimulants for this purpose and then summarized published literature that explores whether stimulants actually improve specific aspects of neurocognitive function. Although calling for more research, they tentatively concluded that stimulants indeed may be "smart pills" for some people under certain circumstances. This comment emphasizes that they never actually defined the desired qualities of a smart pill, seemed to accept the unproven axiom that slight improvements in specific tests constitute meaningful enhancement of intelligence, and failed to consider the possible costs to individuals and to society of promoting the use of this class of medications for such a purpose.     

Modulation of the conflict monitoring intensity: The role of aversive reinforcement,cognitive demand,and trait-BIS

According to Botvinick’s (2007) integrative account, conflict monitoring is aversive because individuals anticipate cognitive demand, whereas the revised reinforcement sensitivity theory (rRST) predicts that conflict processing is aversive because individuals anticipate aversive reinforcement of erroneous responses. Because these accounts give different reasons for the aversive aspects of conflict, we manipulated cognitive demand and the aversive reinforcement as a consequence of wrong choices in a go/no-go task. Thereby, we also aimed to investigate whether individual differences in conflict sensitivity (i.e., in trait anxiety, linked to high sensitivity of the behavioral inhibition system [trait-BIS]) represent the effects of aversive reinforcement and cognitive demand in conflict tasks. We expected that these manipulations would have effects on the frontal N2 component representing activity of the anterior cingulate cortex. Moreover, higher-trait-BIS individuals should be more sensitive than lower-trait-BIS individuals to aversive effects in conflict situations, resulting in a more negative frontal N2 for higher-trait-BIS individuals. In Study 1, with N = 104 students, and Study 2, with N = 47 students, aversive reinforcement was manipulated in three levels (within-subjects factor) and cognitive demand in two levels (between-subjects factor). The behavioral findings from the go/no-go task with noncounterbalanced reinforcement levels (Study 1) could be widely replicated in a task with counterbalanced reinforcement levels (Study 2). The frontal mean no-go N2 amplitude and the frontal no-go N2 dipole captured predicted reinforcement-related variations of conflict monitoring, indicating that the anticipation of aversive reinforcement induces variations in conflict monitoring intensity in frontal brain areas. The aversive nature of conflict was underlined by the more pronounced conflict monitoring in higher- than in lower-trait-BIS individuals.     

Reversing the word-length effect: A comment on Caplan, Rochon, and Waters

Caplan, Rochon, and Waters (1992) report a failure to observe the poorer immediate serial recall for words of longer spoken duration obtained by Baddeley, Thomson, and Buchanan (1975) and subsequently replicated by others. Indeed, they find a significant reversal of this effect. We present evidence that the material used by Caplan et al. differs only minimally in spoken duration under speeded articulation conditions (Exp. 1 = 1.9%, Exp 2 = 2.31%), in contrast to a clear difference in the case of the original Baddeley et al. material (24.5%). It is further suggested that the reversal of the word-length effect may result from differences in acoustic similarity between the “long” and “short” word sets used by Caplan et al. We conclude that the evidence continues to indicate that longer spoken duration is associated with reduced memory span.     

Hypnotic suggestion modulates cognitive conflict: the case of the flanker compatibility effect

The present work was aimed at investigating whether the flanker compatibility effect can be eliminated by means of a posthypnotic suggestion influencing attentional focusing. In Experiment 1, participants who scored high and low on hypnotic susceptibility performed the flanker compatibility task when naturally awake and when under a posthypnotic suggestion aimed at increasing the target's discriminability from the flankers. Results showed that the posthypnotic suggestion effectively eliminated the flanker compatibility effect in highly susceptible participants, whereas low-susceptibility participants did not show any reduction in the effect. In Experiment 2, highly susceptible participants performed the task after receiving a suggestion but without the induction of hypnosis. Results showed that the suggestion alone was not sufficient to reduce the flanker compatibility effect. These results support the view that in highly susceptible participants, hypnotic suggestion can influence the ability to focus on relevant information.     

Adolescent triangulation into interparental conflict: Role of cognitive appraisals and birth-order

ABSTRACT

Triangulation of adolescents into interparental conflict has since long been recognized as a risk factor for adolescents’ psychological adjustment. However, there is a scarcity in research focusing on exploring the variables that make adolescents more vulnerable to get triangulated. This study used a cross-section research design to examine the relationship between interparental conflict and adolescent triangulation into that conflict in an under-researched population of Pakistani school going adolescents (N = 521), with an age range of 13-19 years (M = 15.25; SD = 1.46); while exploring the role of adolescent’s cognitive appraisals (threat and self-blame) and birth-order. The results indicated that interparental conflict, appraisal of threat and appraisal of self-blame are significant predictors of adolescent triangulation. Moreover, this study also revealed the moderating role of adolescent birth order in the relationship between interparental conflict and triangulation, as well as between appraisal of self-blame and triangulation; indicating that the ‘only’ child in the family was at the highest risk of being triangulated into their parents’ arguments, while the youngest child was least likely to get involved.

Testing the validity of conflict drift-diffusion models for use in estimating cognitive processes: A parameter-recovery study

Researchers and clinicians are interested in estimating individual differences in the ability to process conflicting information. Conflict processing is typically assessed by comparing behavioral measures like RTs or error rates from conflict tasks. However, these measures are hard to interpret because they can be influenced by additional processes like response caution or bias. This limitation can be circumvented by employing cognitive models to decompose behavioral data into components of underlying decision processes, providing better specificity for investigating individual differences. A new class of drift-diffusion models has been developed for conflict tasks, presenting a potential tool to improve analysis of individual differences in conflict processing. However, measures from these models have not been validated for use in experiments with limited data collection. The present study assessed the validity of these models with a parameter-recovery study to determine whether and under what circumstances the models provide valid measures of cognitive processing. Three models were tested: the dual-stage two-phase model (Hübner, Steinhauser, & Lehle, Psychological Review, 117(3), 759–784, 2010), the shrinking spotlight model (White, Ratcliff, & Starns, Cognitive Psychology, 63(4), 210–238, 2011), and the diffusion model for conflict tasks (Ulrich, Schröter, Leuthold, & Birngruber, Cogntive Psychology, 78, 148–174, 2015). The validity of the model parameters was assessed using different methods of fitting the data and different numbers of trials. The results show that each model has limitations in recovering valid parameters, but they can be mitigated by adding constraints to the model. Practical recommendations are provided for when and how each model can be used to analyze data and provide measures of processing in conflict tasks.     

Alcohol and cognitive control: implications for regulation of behavior during response conflict

Alcohol intoxication often leads to dysregulated behavior in contexts characterized by conflict between prepotent response tendencies and incompatible alternative responses. Recent research has identified 2 components of an anterior executive attention system that are essential for adaptive behavior when response conflict exists. Event-related potential (ERP) measures of evaluative and regulative cognitive control were collected to determine if impaired executive attention was responsible for observed behavior deficits when intoxicated. Intoxicated participants displayed task performance deficits on incongruent color-naming trials relative to sober controls. Alcohol did not affect P3 magnitude/latency, indicating that timing and integrity of stimulus evaluation remained intact. In contrast, alcohol did reduce frontal components of ERP that index evaluative and regulative cognitive control processes.
