Deep thinking increases task-set shielding and reduces shifting flexibility in dual-task performance

Performing two tasks concurrently is difficult, which has been taken to imply the existence of a structural processing bottleneck. Here we sought to assess whether and to what degree one's multitasking abilities depend on the cognitive-control style one engages in. Participants were primed with creativity tasks that either called for divergent thinking-which were suspected to induce a holistic, flexible task processing mode, or convergent thinking-which were assumed to induce a systematic, focused processing mode. Participants showed reduced cross-talk between tasks and increased task-component switching costs (dual-task costs) for the convergent-thinking group compared to both, a divergent-thinking group and a neutral control group. The results suggest that the cognitive-control style people engage in prior to the task predicts their multitasking performance.     

A claw is like my hand: comparison supports goal analysis in infants

Understanding the intentional relations in others' actions is critical to human social life. Origins of this knowledge exist in the first year and are a function of both acting as an intentional agent and observing movement cues in actions. We explore a new mechanism we believe plays an important role in infants' understanding of new actions: comparison. We examine how the opportunity to compare a familiar action with a novel, tool use action helps 7- and 10-month-old infants extract and imitate the goal of a tool use action. Infants given the chance to compare their own reach for a toy with an experimenter's reach using a claw later imitated the goal of an experimenter's tool use action. Infants who engaged with the claw, were familiarized with the claw's causal properties, or learned the associations between claw and toys (but did not align their reaches with the claw's) did not imitate. Further, active participation in the familiar action to be compared was more beneficial than observing a familiar and novel action aligned for 10-month-olds. Infants' ability to extract the goal-relation of a novel action through comparison with a familiar action could have a broad impact on the development of action knowledge and social learning more generally.     

Emotion, directed forgetting, and source memory

We investigated the role of emotion on item and source memory using the item method of directed forgetting (DF) paradigm. We predicted that emotion would produce source memory impairment because emotion would make it more difficult to distinguish between to-be-remembered (R items) and to-be-forgotten items (F items) by making memory strength of R and F items similar to each other. Participants were presented with negatively arousing, positively arousing, and neutral pictures. After each picture, they received an instruction to remember or forget the picture. At retrieval, participants were asked to recall both R and F items and indicate whether each item was an R or F item. Recall was higher for the negatively arousing than for the positively arousing or neutral pictures. Further, DF occurred for the positively arousing and neutral pictures, whereas DF was not significant for the negatively arousing pictures. More importantly, the negatively arousing pictures, particularly the ones with violent content, showed a higher tendency of producing misattribution errors than the other picture types, supporting the notion that negative emotion may produce source memory impairment, even though it is still not clear whether the impairment occurs at encoding or retrieval.     

TRIAL-BASED FUNCTIONAL ANALYSIS AND FUNCTIONAL COMMUNICATION TRAINING IN AN EARLY CHILDHOOD SETTING

Problem behavior is common in early childhood special education classrooms. Functional communication training (FCT; Carr & Durand, 1985 ) may reduce problem behavior but requires identification of its function. The trial‐based functional analysis (FA) is a method that can be used to identify problem behavior function in schools. We conducted trial‐based FAs and FCT with 3 children in an early childhood special education setting. All trial‐based FAs resulted in identification of behavioral functions, and subsequent FCT led to reductions in problem behavior and increases in communication.     

Mangy mutt or furry friend? Anthropomorphism promotes animal welfare

Recent research has demonstrated that people have an affinity for non-human entities that appear to have human qualities. The current studies build on this research, examining whether anthropomorphism can be used to promote animal welfare. In Study 1 (n = 42), participants read scenarios about dogs and reported more willingness to help the ones described with anthropomorphic language relative to those described with non-anthropomorphic language. In Study 2 (n = 57), participants rated dogs on either human or canine characteristics (e.g., good listener vs. good at listing to commands). Relative to the non-anthropomorphism condition, participants in the anthropomorphism condition reported more willingness to adopt dogs from a shelter, and more support for animal rights, animal welfare, and vegetarian and vegan attitudes. Moreover, these pro-animal attitudes fully mediated the effect of the anthropomorphism manipulation on willingness to adopt the dogs.     

How we know what we intend

How do we know what our intentions are? It is argued that work on self-knowledge has tended to neglect the attitude of intention, and that an epistemological account is needed that is attuned to the specific features of that state. Richard Moran??s ??Authorship?? view, on which we can acquire self-knowledge by making up our minds, offers a promising insight for such an account: we do not normally discover what we intend through introspection. However, his formulation of the Authorship view, developed primarily with the attitude of belief in mind, is found wanting when applied to intention. An alternative account is proposed for knowledge of one??s own intentions that gives a central role to the mental act of deciding what to do. It is argued that we can come to know what we intend by making a decision about what to do and self-ascribing the content of that decision as our intended action.     

Mental states inside out: Switching costs for emotional and nonemotional sentences that differ in internal and external focus

Mental states—such as thinking, remembering, or feeling angry, happy, or dizzy—have a clear internal component. We feel a certain way when we are in these states. These internal experiences may be simulated when people understand conceptual references to mental states. However, mental states can also be described from an “external” perspective, for example when referring to “smiling.” In those cases, simulation of visible outside features may be more relevant for understanding. In a switching costs paradigm, we presented semantically unrelated sentences describing emotional and nonemotional mental states while manipulating their internal or external focus. The results show that switching costs occur when participants shift between sentences with an internal and an external focus. This suggests that different forms of simulation underlie understanding these sentences. In addition, these effects occurred for emotional and nonemotional mental states, suggesting that they are grounded in a similar way—through the process of simulation.     

Conflict Transformation, Stigma, and HIV-Preventive Structural Change

Over the prior decade, structural change efforts have become an important component of community-based HIV prevention initiatives. However, these efforts may not succeed when structural change initiatives encounter political resistance or invoke conflicting values, which may be likely when changes are intended to benefit a stigmatized population. The current study sought to examine the impact of target population stigma on the ability of 13 community coalitions to achieve structural change objectives. Results indicated that coalitions working on behalf of highly stigmatized populations had to abandon objectives more often than did coalitions working for less stigmatized populations because of external opposition to coalition objectives and resultant internal conflict over goals. Those coalitions that were most successful in meeting external challenges used opposition and conflict as transformative occasions by targeting conflicts directly and attempting to neutralize oppositional groups or turn them into strategic allies; less successful coalitions working on behalf of stigmatized groups struggled to determine an appropriate response to opposition. The role of conflict transformation as a success strategy for working on behalf of stigmatized groups is discussed.     

Looking like a criminal: Stereotypical black facial features promote face source memory error

The present studies tested whether African American face type (stereotypical or nonstereotypical) facilitated stereotype-consistent categorization, and whether that categorization influenced memory accuracy and errors. Previous studies have shown that stereotypically Black features are associated with crime and violence (e.g., Blair, Judd, & Chapleau Psychological Science 15:674?C679, 2004; Blair, Judd, & Fallman Journal of Personality and Social Psychology 87:763?C778, 2004; Blair, Judd, Sadler, & Jenkins Journal of Personality and Social Psychology 83:5?C252002); here, we extended this finding to investigate whether there is a bias toward remembering and recategorizing stereotypical faces as criminals. Using category labels, consistent (or inconsistent) with race-based expectations, we tested whether face recognition and recategorization were driven by the similarity between a target??s facial features and a stereotyped category (i.e., stereotypical Black faces associated with crime/violence). The results revealed that stereotypical faces were associated more often with a stereotype-consistent label (Study 1), were remembered and correctly recategorized as criminals (Studies 2?C4), and were miscategorized as criminals when memory failed. These effects occurred regardless of race or gender. Together, these findings suggest that face types have strong category associations that can promote stereotype-motivated recognition errors. Implications for eyewitness accuracy are discussed.     

Forgetting in context: The effects of age, emotion, and social factors on retrieval-induced forgetting

Retrieval-induced forgetting (RIF) refers to the finding that selectively retrieving some information impairs subsequent memory for related but nonretrieved information. This occurs both for the individual doing the remembering (i.e., within-individual retrieval-induced forgetting: WI-RIF), as well as for individuals merely listening to those recollections (i.e., socially shared retrieval-induced forgetting: SS-RIF). In the present study, we examined how the contextual factors of age and emotion independently and interactively affect both WI-RIF and SS-RIF. The results indicated that both WI-RIF and SS-RIF occurred at equivalent levels, both for younger and older adults and for neutral and emotional information. However, we identified a boundary condition to this effect: People only exhibited SS-RIF when the speaker that they were listening to was of the same sex as themselves. Given that participants reported feeling closer to same-sex speakers, this suggests that people co-retrieve more, and therefore exhibit increased SS-RIF, with close others. In everyday life, these RIF effects should influence what information is remembered versus forgotten in individual and collective memories.
