The tendency to discount future prospects in lieu of smaller immediate outcomes is known as temporal discounting. The current work used eye‐tracking methodology to examine attentional processing to different elements of choice during an intertemporal decision task. Our findings reveal that those who tend to prefer the immediate option demonstrate attentional biases that were predictive of choice. When losses were at stake, selective attention biases also predicted unique variance in self‐report measures of risk taking, impulsivity, and self‐control beyond what was accounted for by a discounting parameter (k), a typical method for summarizing intertemporal choice data. Overall, our findings suggest that eye‐tracking measures of selective attention may allow for a better theoretical understanding of the mechanisms and processes involved in intertemporal choice.

A sex-balanced sample (N = 96) of children from age 6.5 to age 12.5 completed a modified Attention Network Test. Across these ages, we found evidence for developmental changes to alerting and executive control but stable orienting. Additionally, we found that the youngest members of our sample manifested an interaction between alerting and executive control that is opposite to that typically found in adults; a reversal that diminishes with age to achieve the adult pattern by the older end of the age range of our sample. 相似文献

This study examined associations among low‐income mothers' use of attention‐getting utterances during shared book reading, preschoolers' verbal engagement and visual attention to reading, and their early literacy skills (N = 51). Mother–child shared book reading sessions were videotaped and coded for each utterance, including attention talk, contextualized talk, de‐contextualized talk, and print talk. Preschoolers' attention during book reading was assessed using two measures: verbal engagement by using a rating scale of preschoolers' involvement in book reading discussion and visual attention by coding visual gaze. Findings indicated that mothers' attention talk was positively associated with children's verbal engagement, while maternal print talk was associated with children's visual attention. Further, low‐level maternal print talk was associated with higher early decoding scores of children when it was accompanied with high‐level maternal attention talk.

Efficient cognitive control is implicated in tic control in young people with Tourette syndrome (TS). Attention‐deficit/hyperactivity disorder (ADHD) frequently co‐occurs with TS and is associated with impaired cognitive control. Young people with TS and ADHD (TS+ADHD) show poorer cognitive control performance than those with TS, but how co‐occurring ADHD affects underlying neural activity is unknown. We investigated this issue by examining behavioural and event‐related potential (ERP) correlates of cognitive control in young people with these conditions. Participants aged 9–17 with TS (n = 17), TS+ADHD (n = 17), ADHD (n = 11), and unaffected controls (n = 20) performed a visual Go/Nogo task during electroencephalography (EEG) recording. Behavioural performance measures (D‐prime, RT, reaction time variability, post‐error slowing) and ERP measures (N2, P3, error‐related negativity (ERN), error positivity (Pe)) were analysed in a 2 (TS‐yes, TS‐no) × 2 (ADHD‐yes, ADHD‐no) factorial analysis to investigate the effects of TS, ADHD, and their interaction. The results of these analyses showed that ADHD was associated with poorer performance and reduced amplitude of all ERPs, reflecting widespread cognitive control impairments. Tourette syndrome was associated with slowed RTs, which might reflect a compensatory slowing of motor output to facilitate tic control. There was no interaction between the TS and ADHD factors for any behavioural or ERP measure, indicating the impairing effects of ADHD on behaviour and electrophysiological markers of cognitive control were present in TS+ADHD and that RT slowing associated with TS was unaffected by co‐occurring ADHD symptoms. 相似文献

Are the effects of memory and attention on perception synergistic, antagonistic, or independent? Tested separately, memory and attention have been shown to affect the accuracy of orientation judgements. When multiple stimuli are presented sequentially versus simultaneously, error variance is reduced. When a target is validly cued, precision is increased. What if they are manipulated together? We combined memory and attention manipulations in an orientation judgement task to answer this question. Two circular gratings were presented sequentially or simultaneously. On some trials a brief luminance cue preceded the stimuli. Participants were cued to report the orientation of one of the two gratings by rotating a response grating. We replicated the finding that error variance is reduced on sequential trials. Critically, we found interacting effects of memory and attention. Valid cueing reduced the median, absolute error only when two stimuli appeared together and improved it to the level of performance on uncued sequential trials, whereas invalid cueing always increased error. This effect was not mediated by cue predictiveness; however, predictive cues reduced the standard deviation of the error distribution, whereas nonpredictive cues reduced “guessing”. Our results suggest that, when the demand on memory is greater than a single stimulus, attention is a bottom-up process that prioritizes stimuli for consolidation. Thus attention and memory are synergistic. 相似文献

Li and Baroody present a study in which they investigate toddlers’ spontaneous attention to exact quantity without acknowledging how previous studies of spontaneous focusing on numerosity (SFON) are related to their concept and methods. In this commentary requested by the European Journal of Developmental Psychology, we argue that the concept and the methods of spontaneous attention to exact quantity in the study of Li and Baroody clearly arise from previous research on SFON, as the authors have previously noted in their paper published in 2008. It is highly questionable whether their approach can be theoretically or methodologically dissociated from the previous research on SFON tendency to the extent that it is necessary to use an alternative name for the concept in their study. 相似文献

Li and Baroody presented a study in which they investigate children’ spontaneous attention to exact quantity without acknowledging how previous studies of spontaneous focusing on numerosity (SFON) are related to their concept and methods. The authors’ reaction to our pointing this out makes it is clear that SFON research has had foundational role in the development of Baroody and his colleagues spontaneous attention to number (SAN) idea. Thus the authors must acknowledge the SFON literature as the substantial part of their theoretical and methodological construct. The latest definition of SAN states this undeniably. “SAN is the attentional process that underlies exact number recognition initiated by the mathematical thinking triggered by SFON (e.g., attention to “threeness” directed by conceptual knowledge of “three” activated by SFON).” Furthermore, in their response, Dr Baroody and Dr Li admit that “An awareness of the SFON literature did help us explicitly recognize that, given the ambiguous instructions that do not explicitly direct a child’s attention to number, both the nonverbal production and matching tasks were useful in assessing unguided or spontaneous attention to a number.” It is surprising that in their response to the European Journal of Educational Psychology, the authors maintain their claim that they have cited the SFON literature adequately in their study about SAN. 相似文献

The present study was designed to gather validity data on the Devereux Scales of Mental Disorders (DSMD) for distinguishing among children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD; N = 32), Conduct Disorder (CD; N = 34), or no clinical diagnosis (NC; N = 65). Three types of indicators were compared: (a) DSMD scale, composite, and total scores, (b) the number of ADHD or CD-related items endorsed, and (c) diagnostic efficiency statistics (e.g., sensitivity, positive and negative predictive power). The clinical groups did not differ significantly from each other, but both were significantly higher than the NC group on all DSMD scales. Moreover, there were significant differences between the ADHD and the CD groups on the number of respective ADHD and CD-related items endorsed. A cut-off of seven to eight items yielded the best discrimination between the two diagnostic groups. Diagnostic efficiency statistics indicate that the DSMD may be effective at differentiating between similar disruptive behavior disorders. 相似文献

Testing joint attention, imitation, and play as infancy precursors to language and theory of mind 总被引:1,自引:0,他引:1

Various theoretical accounts propose that an important developmental relation exists between joint attention, play, and imitation abilities, and later theory of mind ability. However, very little direct empirical evidence supports these claims for putative “precursor” theory of mind status. A small sample (N=13) of infants, for whom measures of play, joint attention, and imitation had been collected at 20 months of age, was followed-up longitudinally at 44 months and a battery of theory of mind measures was conducted. Language and IQ were measured at both timepoints. Imitation ability at 20 months was longitudinally associated with expressive, but not receptive, language ability at 44 months. In contrast, only the joint attention behaviours of gaze switches between an adult and an active toy and looking to an adult during an ambiguous goal detection task at 20 months were longitudinally associated with theory of mind ability at 44 months. It is argued that joint attention, play, and imitation, and language and theory of mind, might form part of a shared social–communicative representational system in infancy that becomes increasingly specialised and differentiated as development progresses. 相似文献
