The Development of Internal State Language during the Third Year of Life: A Longitudinal Parent Report Study

Children's talk about the mind has been scarcely studied in non‐English speakers. For this reason, this longitudinal study documents age‐related changes in German‐speaking children's internal state language. At 24, 30 and 36 months, children were administered general language tests and their internal state vocabulary levels were obtained via parental report. The developmental transition from a vocabulary rich in physiological, perceptual and desire terms to a vocabulary rich in a wider range of mental concepts confirmed previous research with French‐speaking and English‐speaking children and research in children's internal state comprehension. Further, children's category scores proved to be developmentally stable. Finally, with increasing age, children's category scores became more specifically related to each other, independent of general language skills. The results are discussed in regard to the universality of children's talk about the mind. Copyright © 2012 John Wiley & Sons, Ltd.     

Those Easily Forgotten: The Impact of Emigration on Those Left Behind

Much has been written about the experiences and stresses of those who emigrate. By contrast, little attention has been paid to the experiences of those who stay behind—family members and friends who for various reasons do not to join their loved ones in the destination country. In this article, I describe the experiences of some South Africans whose families and friends have emigrated. This study forms part of a larger research project focusing on the impact of emigration on South African family life. Twenty‐one participants were interviewed by means of a semistructured interview at least 6 months after one or more family member(s) and/or friend(s) left South Africa, to explore participants’ experiences around their loved ones’ emigration. A thematic analysis of the data reveals that those left behind experience various emotions, ranging from emotional ambivalence to anger and distress. Emigration is mostly experienced as a vast loss, almost akin to a “death,” bringing about significant changes in social networks and relationships. The therapeutic significance of the findings for those working with emigrant families is also explored.     

Social embeddedness and economic opportunism: a game situation

According to Evolutionary Game Theory, multiple exchanges with partners are necessary to foster cooperation. Multiple exchanges with partners tend to enhance the good experience of the partners and the predictability of their behaviour and should therefore increase cooperativeness. This study explored whether social embeddedness, or the preference for close and stable social relationships, a variable which tends to increase multiple exchanges, is associated with more cooperative attitudes; and whether social embeddedness increases cooperative behavior towards unknown partners in a game situation. The first study, with 169 undergraduates, indicated that social embeddedness (preference for close and durable social relations) was negatively associated with opportunistic attitudes. The second study had a sample of 60 undergraduates playing a Trust Game with unknown partners and showed that self-reported social embeddedness was positively correlated with scores for cooperative economic behavior towards the partners. These results highlight the relationships of social embeddedness with cooperative attitudes and behaviour.     

Links between self-reported and laboratory behavioral impulsivity

Havik, M., Jakobson, A., Tamm, M., Paaver, M., Konstabel, K., Uusberg, A., Allik, J., Ööpik, V. & Kreegipuu, K. (2012). Links between self‐reported and laboratory behavioral impulsivity. Scandinavian Journal of Psychology 53, 216–223. A major problem in the research considering impulsivity is the lack of mutual understanding on how to measure and define impulsivity. Our study examined the relationship between self‐reported impulsivity, behavioral excitatory and inhibitory processes and time perception. Impulsivity – fast, premature, thoughtless or disinhibited behavior – was assessed in 58 normal, healthy participants (30 men, mean age 21.9 years). Self‐reported impulsivity as measured by Adaptive and Maladaptive Impulsivity Scale (AMIS) and behavioral excitatory and inhibitory processes as measured by Stop Signal Task were not directly related. Time perception, measured by the retrospective Time Estimation Task, was related to both. The length of the perceived time interval was positively correlated to AMIS Disinhibition subscale and negatively to several Stop Signal Task parameters. The longer subjects perceived the duration to last, the higher was their score on Disinhibition scale and the faster were their reactive responses in the Stop Signal Task. In summary our findings support the idea of cognitive tempo as a possible mechanism underlying impulsive behavior.     

Emotional cues do not increase the likelihood of tip-of-the-tongue states

In a recent article, Schwartz (Psychonomic Bulletin & Review 17:82?C87, 2010) reported the effects of emotion on tip-of-the-tongue states (TOTs). He found increased TOTs for emotion-inducing questions, as well as a carryover effect in which high TOT rates were observed following emotion-inducing questions. In the present study, we sought to replicate these findings while controlling for word frequency, but we found an increased TOT rate neither for emotion-inducing questions nor following emotion-inducing questions. We report three attempts to replicate Schwartz??s (Psychonomic Bulletin & Review 17:82?C87, 2010) effect that focused on systematic differences in word frequency between stimulus sets in the original study; none of the key findings reported by Schwartz (Psychonomic Bulletin & Review 17:82?C87, 2010) were found in any of the experiments. These results fail to support prior claims concerning the effects of emotion on TOTs Schwartz (Psychonomic Bulletin & Review 17:82?C87, 2010). The discussion focuses on the importance of controlling for systematic differences in word characteristics between groups of items.     

Right-hemispheric cortical contributions to language ability in healthy adults

In this study we investigated the correlation between individual linguistic ability based on performance levels and their engagement of typical and atypical language areas in the brain. Eighteen healthy subjects between 21 and 64 years participated in language ability tests, and subsequent functional MRI scans measuring brain activity in response to a sentence completion and a word fluency task. Performance in both reading and high-level language tests correlated positively with increased right-hemispheric activation in the inferior frontal gyrus (specifically Brodmann area 47), the dorsolateral prefrontal cortex (DLPFC), and the medial temporal gyrus (Brodmann area 21). In contrast, we found a negative correlation between performance and left-hemispheric DLPFC activation.Our findings indicate that the right lateral frontal and right temporal regions positively modulate aspects of language ability.     

Priming the mental time line

Growing experimental evidence suggests that temporal events are represented on a mental time line, spatially oriented from left to right. Support for the spatial representation of time comes mostly from studies that have used spatially organized responses. Moreover, many of these studies did not avoid possible confounds attributable to target stimuli that simultaneously convey both spatial and temporal dimensions. Here we show that task-irrelevant, lateralized visuospatial primes affect auditory duration judgments. Responses to short durations were faster when the auditory target was paired with left- than with right-sided primes, whereas responses to long durations were faster when paired with right- than with left-sided primes. Thus, when the representations of physical space and time are concurrently activated, physical space may influence time even when a lateralized, spatially encoded response is not required by the task. The time-space interaction reported here cannot be ascribed to any Spatial-Temporal Association of Response Codes effect. It supports the hypothesis that the representation of time is spatially organized, with short durations represented on the left space and longer ones on the right.     

Eye gaze versus arrows as spatial cues: two qualitatively different modes of attentional selection

This study aimed to evaluate the type of attentional selection (location- and/or object-based) triggered by two different types of central noninformative cues: eye gaze and arrows. Two rectangular objects were presented in the visual field, and subjects' attention was directed to the end of a rectangle via the observation of noninformative directional arrows or eye gaze. Similar experiments with peripheral cues have shown an object-based effect: faster target identification when the target is presented on the cued object as compared to the uncued object, even when the distance between target and cue was the same. The three reported experiments aimed to compare the location- and object-based attentional orienting observed with arrows and eye gaze, in order to dissociate the orienting mechanisms underlying the two types of orienting cues. Results showed similar cueing effects on the cued versus oppositely cued locations for the two cue types, replicating several studies with nonpredictive gaze and arrow cues. However, a pure object-based effect occurred only when an arrow cue was presented, whereas a pure location-based effect was only found for eye-gaze cues. It is suggested that attention is nonspecifically directed to nearby objects when a noninformative arrow is used as cue, whereas it is selectively directed to a specific cued location when noninformative eye gaze is used. This may be mediated by theory of mind mechanisms.     

Cue and target processing modulate the onset of inhibition of return

Inhibition of return (IOR) is modulated by task set and appears later in discrimination tasks than in detection tasks. Several hypotheses have been suggested to account for this difference. We tested three of these hypotheses in two experiments by examining the influence of cue and target level of processing on the onset of IOR. In the first experiment, participants were required to respond to both the cue and target. The pattern of results showed that deeper processing of the cue or target advanced the onset of IOR. In the second experiment, participants were not required to respond to the cue and a reverse pattern of results emerged, which replicated the general findings in cuing tasks. We conclude that in more-demanding tasks, an additional process slows down the processing of a nonpredictive cue in order to enhance the processing of the target.
