A pelmanism (matched-pairs) game was used in order to test the hypothesis that survival-relevant stimuli that are likely to have been present during human evolution (e.g., a snake in attack position) enjoy a memory advantage over other survival-relevant (but “modern”) stimuli (e.g., a threatening image of a gunman). Survival-relevant stimuli were matched for arousal and presented in one of two 5 x 4 grids, along with filler items. Participants were asked to match the pairs in the grids by clicking on successive squares to reveal stimuli. Participants made significantly fewer errors when matching evolutionarily relevant survival stimuli than when matching the other stimuli. Additionally, on incorrect trials, the attempted matches were significantly closer to the actual locations of evolutionarily relevant targets than to those of other stimuli. The results suggest that objects that likely posed a consistent threat throughout human evolutionary history are better remembered than other, equally arousing and survival-relevant, stimuli.

Using a sample of 263 mother–child dyads, we examined the extent to which maternal emotional and cognitive support during a joint problem‐solving task when children were 3‐years‐old predicted children's academic skills 1 year later independent of each other, the quality of the home learning environment, and maternal emotional responsiveness. When all parenting measures were examined simultaneously, only maternal emotional support during problem solving and the quality of the home learning environment predicted unique variation in gains in pre‐academic skills from 3 to 4 years of age. The positive effect of emotional support during problem solving was especially apparent for children whose pre‐academic skills were low at the age of 3 years. These findings are discussed in light of the changing demands placed on young children and their parents as they prepare for entry to the formal school system.

Previous research has demonstrated that talk about immigration can function to produce, reproduce and stabilize racism (Capdevila & Callaghan, 2008 ). In New Zealand (NZ), changes in immigration policy have seen a rapid increase in diverse groups of migrants with varied cultural backgrounds entering the country in the past two decades. Given its unique colonial history and ‘settler nationality in a bicultural nation’ (Bell, 2009 ), we explored how young NZ adults talk about and produce meanings and understandings of immigration, immigrants and cultural diversity. Appealing to notions of NZ as ‘one society’, as English speaking, and as English looking participants constructed NZ, NZ national identity and the NZ economy in particular ways. This constituted a nationalist rhetoric that was taken up in common‐sense ways by participants to legitimize racist talk whilst simultaneously acting to locate participants themselves as reasonable and moral individuals. It is concluded that nationalist discourses function to reinforce patterns of social dominance and perpetuate the notion of New Zealanders as largely white, European‐looking and English‐speaking.

Mismatch negativity and the P300 have been investigated as electrophysiological indices of behavioral auditory discrimination of duration. Using an oddball paradigm, responses were evoked to stimuli that had been behaviorally demonstrated to be either perceptible or imperceptible. The results indicated P300 events were present with the perceptible contrast but absent for the imperceptible contrast with all participants, while mismatch negativities were present in approximately 80 and 20% of participants to the perceptible and imperceptible contrasts, respectively. The present study extended the findings by applying the same paradigm to the discrimination of spectral and amplitude contrasts. 10 young adults with normal hearing were participants. Assuming that auditory assessment should involve representation and processing in all acoustic domains (i.e., temporal/duration, spectral/frequency, and amplitude/intensity), the effects seen with temporal contrasts were predicted to be similar for spectral and amplitude contrasts. The findings generally illustrated that the P300 was more accurate than the mismatch negativity in reflecting behavioral discrimination. Together, these studies challenge the use of mismatch negativity as an electrophysiological correlate for behavioral discrimination of auditory perceptible contrasts. 相似文献

Two experiments examined biases in children's (5/6- and 7/8-year-olds) and adults' moral judgments. Participants at all ages judged that it was worse to produce harm when harm occurred (a) through action rather than inaction (omission bias), (b) when physical contact with the victim was involved (physical contact principle), and (c) when the harm was produced as a direct means to an end rather than as an unintended but foreseeable side effect of the action (intention principle). The youngest participants, however, did not incorporate benefit when making judgments about situations in which harm to one individual resulted in benefit to five individuals. Older participants showed some preference for benefit resulting from action (commission) as opposed to inaction (omission). The findings are discussed in the context of the theory that moral judgments result, in part, from the operation of an inherent, intuitive moral faculty compared with the theory that moral judgments require development of necessary cognitive abilities. 相似文献

The Attachment and Clinical Issues Questionnaire (ACIQ; M. A. Lindberg & S. W. Thomas, 2011), was developed over an 18-year period containing 29 scales. The purpose of the present study was to test (a) the validity of the attachment scales in terms of how they predict to whom one turns in times of stress and for affective sharing, and (b) how the attachment scales compared with the Experiences in Close Relationship Questionnaire (ECR) in terms of concurrent, convergent, and discriminant evidence. The relevant secure scales of the ACIQ predicted to whom one turned in study 1, and study 2 demonstrated good convergent evidence with the ECR, but superior concurrent evidence in predicting partner satisfaction, and superior discriminant evidence in differentially correlating with mother and father warmth. Thus, the ACIQ passed essential validity and psychometric tests and was a more robust measure than the ECR with these defining characteristics of attachment. 相似文献

Visual attention has temporal limitations. In the attentional blink (AB) a stream of stimuli such as letters or digits are presented to a participant on a computer monitor at a rapid rate. Embedded in the stream are two targets that the participant must try to identify. Identification of the second target is severely impaired if it is presented within approximately 500ms of the first target. This is the 'blink' in visual attention. In this study we examined the role of the magnocellular visual pathway in the AB. This fast conducting pathway has high temporal resolution and contrast sensitivity. It is also insensitive to the direction of chromatic contrast, and this attribute was exploited in order to isolate its contributions to temporal attention. Colour defined, luminance noise masked AB streams were compared to AB streams of varying achromatic contrast. The four observers, (2F and 2M) aged between 21 and 35years, had normal visual acuity and colour vision. The colour stimuli produced a similar blink to the moderate contrast achromatic stimuli. This indicates that the magnocellular pathway does not have a privileged role in the attentional blink. We provide an explanation of previous apparently contradictory findings in terms of the role of different types of visual masking in the attentional blink. 相似文献
