The development of co-representation effects in a joint task: Do children represent a co-actor?

When two adults jointly perform a task, they often show interference effects whereby the other’s task interferes with their own performance (Sebanz, Knoblich, & Prinz, 2003). The current study investigated whether these co-representation effects can be observed in young children. This phenomenon can be used as a criterion for adult-like joint action in children, which has been under debate in existing literature due to the difficulty in identifying what mechanisms underlie the behaviours observed (Brownell, 2011). In Experiment 1, two children performed an adapted Bear Dragon task (Kochanska, Murray, Jacques, Koenig, & Vandegeest, 1996), where children were required to point to a picture when instructed to do so by one puppet and to inhibit pointing when instructed to by the other. In the Same Task condition, both children in a pair were asked to respond to the same puppet, whereas in the Different Task condition, they were asked to respond to different puppets. Children made more errors in the Different Task condition than the Same Task, suggesting that they were experiencing interference from their partner’s task rule. In Experiment 2 children in Different and Same task conditions began with the same task as in Experiment 1 and then switched which puppet to respond to. Switch costs were lower in the Different task condition, consistent with children having already represented the alternative task rule on behalf of their partner during the pre-switch phase. Experiment 3 replicated the effect of Task in a novel computer-based paradigm with children between 4 and 5 years, but not younger. These data provide the first direct evidence that children as young as 4 years co-represent a partner's task during a joint activity, and that younger children may not be capable of co-representation.     

Why ‘believes’ is not a vague predicate

According to what I call the ‘Vagueness Thesis’ (‘VT’) about belief, ‘believes’ is a vague predicate. On this view, our concept of belief admits of borderline cases: one can ‘half-believe’ something (Price in Belief, George Allen & Unwin, London, 1969) or be ‘in-between believing’ it (Schwitzgebel in Philos Q 51:76–82, 2001, Noûs 36:249–275, 2002, Pac Philos Q 91:531–553, 2010). In this article, I argue that VT is false and present an alternative picture of belief. I begin by considering a case—held up as a central example of vague belief—in which someone sincerely claims something to be true and yet behaves in a variety of other ways as if she believes that it is not. I argue that, even from the third-person perspective prioritised by proponents of VT, the case does not motivate VT. I present an alternative understanding of the case according to which the person in question believes as they say they do yet also has a belief-discordant implicit attitude otherwise. Moreover, I argue that, independently of the interpretation of any particular case, VT fails to accommodate the first-person perspective on belief. Belief is not only an item of one’s psychology that helps explain one’s behaviour; it is what one takes to be true. This fact about belief manifests itself in the nature of deliberation concerning whether to believe something and that of introspection regarding whether one believes something. Attending to these phenomena reveals that VT is not merely unmotivated, but untenable.     

Auditory attention switching and judgment switching: Exploring multicomponent task representations

An auditory attention-switching paradigm was combined with a judgment-switching paradigm to examine the interaction of a varying auditory attention component and a varying judgment component. Participants heard two dichotically presented stimuli—one spoken by a female speaker and one spoken by a male speaker. In each trial, the stimuli were a spoken letter and a spoken number. A visual explicit cue at the beginning of each trial indicated the auditory attention criterion (speaker sex/ear) to identify the target stimulus (Experiment 1) or the judgment that had to be executed (Experiment 2). Hence, the attentional selection criterion switched independently between speaker sexes (or between ears), while the judgment alternated between letter categorization and number categorization. The data indicate that auditory attention criterion and judgment were not processed independently, regardless of whether the attention criterion or the judgment was cued. The partial repetition benefits of the explicitly cued component suggested a hierarchical organization of the auditory attention component and the judgment component within the task set. We suggest that the hierarchy arises due to the explicit cuing of one component rather than due to a “natural” hierarchy of auditory attention component and judgment component.

Narrative identity in schizophrenia

This study examined narrative identity in a group of 81 patients with schizophrenia and 50 healthy controls through the recall of self-defining memories. The results indicated that patients’ narratives were less coherent and elaborate than those of controls. Schizophrenia patients were severely impaired in the ability to make connections with the self and extract meaning from their memories, which significantly correlated with illness duration. In agreement with earlier research, patients exhibited an early reminiscence bump. Moreover, the period of the reminiscence bump, which is highly relevant for identity development, was characterized by fewer achievements and more life-threatening event experiences, compared with controls. A negative correlation was found between negative symptoms, number of self-event connections and specificity of narratives. Our results suggest that schizophrenia patients have difficulties to organize and extract meaning from their past experiences in order to create coherent personal narratives.     

Computerised Cognitive Behavioural Therapy for the Prevention and Treatment of Depression and Anxiety in Children and Adolescents: A Systematic Review

Research has shown that computerised cognitive behaviour therapy (cCBT) can be effective in the treatment of depression and anxiety in adults, although the outcomes with children and adolescents are unclear. The aim of the study is to systematically review the literature on the effectiveness of cCBT for the prevention and treatment of depression and anxiety in children and adolescents. EMBASE, PsychInfo and Pubmed were searched using specific terms and inclusion criteria for cCBT studies involving young people under the age of 18. A hand search was also conducted, and the authors were contacted to identify additional papers. Ten studies met the inclusion criteria. These included case series and randomised controlled trials concerned with both treatment and prevention. Six different software packages were described that varied in length and the nature and extent of professional contact and supervision. All studies reported reductions in clinical symptoms and also improvements in variables such as behaviour, self-esteem and cognitions. Satisfaction with treatment was moderate to high from both children and parents, though levels of drop out and non-completion were often high. Additional randomised controlled trials are required, as the literature is currently limited. However, preliminary evidence suggests that cCBT is an acceptable and effective intervention for this age group.     

Alcohol intoxicated witnesses' interpretation of social behavior in intimate partner violence

Alcohol intoxication affects social information processing, though research is scarce regarding how alcohol affected eyewitnesses' perception of social interaction within an applied forensic context. In the present study, the effects of alcohol intoxication on eyewitnesses' perception of interaction in intimate partner violence (IPV) were investigated. The participants (n = 152) were randomized to an experimental (alcohol) or control group (juice). After consumption, they viewed a filmed IPV scenario where both interacting parties were confrontational. Afterwards, they rated the involved parties' behavior. Several behaviors were perceived in a similar manner by intoxicated and sober participants, but intoxicated participants perceived both parties' attacking behaviors and some of the man's prosocial behaviors differently than sober participants. Hence, alcohol affected some, but not all, kinds of social behaviors investigated in the present study. This would be of interest to legal praxis and to future studies on intoxicated witnesses to interpersonal violence.     

Temporary ambiguity in whispered word recognition: a semantic priming study

We examined whether listeners use acoustic correlates of voicing to resolve lexical ambiguities created by whispered speech in which a key feature, the voicing, is missing. Three associative priming experiments were conducted. The results showed a priming effect with whispered primes that included an intervocalic voiceless consonant (/petal/ “petal”) when the visual targets (FLEUR “flower”) were presented at the offset of the primes. A priming effect emerged with whispered primes that included a voiced intervocalic consonant (/pedal/ “pedal”) when the delay between the offset of the primes and the visual targets (VELO “bike”) was increased by 50 ms. In none of the experiments, the voiced primes (/pedal/) facilitated the processing of the targets (FLEUR) associated with the voiceless primes (/petal/). Our results suggest that the acoustic correlates of voicing are used by listeners to recover the intended words. Nonetheless, the retrieval of the voiced feature is not immediate during whispered word recognition.
