Many spiders from the salticid subfamily Spartaeinae specialize at preying on other spiders and they adopt complex strategies when targeting these dangerous prey. We tested 15 of these spider‐eating spartaeine species for the capacity to plan detours ahead of time. Each trial began with the test subject on top of a tower from which it could view two boxes: one containing prey and the other not containing prey. The distance between the tower and the boxes was too far to reach by leaping and the tower sat on a platform surrounded by water. As the species studied are known to avoid water, the only way they could reach the prey without getting wet was by taking one of two circuitous walkways from the platform: one leading to the prey (‘correct’) and one not leading to the prey (‘incorrect’). After leaving the tower, the test subject could not see the prey and sometimes it had to walk past the incorrect walkway before reaching the correct walkway. Yet all 15 species chose the correct walkway significantly more often than the incorrect walkway. We propose that these findings exemplify genuine cognition based on representation. 相似文献

The relationship between learned variations in attention and schizotypy was examined in two experiments. In Experiment 1, participants low on a negative subscale of schizotypy exhibited an explicit bias in overt attention towards stimuli that were established as predictive of a trial outcome, relative to stimuli that were irrelevant. The same participants also showed a bias in learning about these stimuli when they presented in a novel context. Neither of these effects was observed in participants high in schizotypy. In Experiment 2, participants low on the negative subscale of schizotypy exhibited faster reaction times towards a target that was cued by a stimulus that had a history of predictive validity relative to a stimulus that had a history of irrelevance. Again, this effect was not present in participants high in schizotypy. These results imply a disruption in the normal allocation of attention to cues that have predictive significance in schizotypy. 相似文献

Whereas adults often rely on explicit memory, children appear to excel in implicit memory, which plays an important role in the acquisition of various cognitive skills, such as those involved in language. The current study aimed to test the assertion of an age‐dependent shift in implicit versus explicit learning within a theoretical framework that explains the link between implicit sequence memory and word‐form acquisition, using the Hebb repetition paradigm. We conducted a one‐year, multiple‐session longitudinal study in which we presented auditory sequences of syllables, co‐presented with pictures of aliens, for immediate serial recall by a group of children (8–9 years) and by an adult group. The repetition of one Hebb sequence was explicitly announced, while the repetition of another Hebb sequence was unannounced and, therefore, implicit. Despite their overall inferior recall performance, the children showed better offline retention of the implicit Hebb sequence, compared with adults who showed a significant decrement across the delays. Adults had gained more explicit knowledge of the implicit sequence than children, but this could not explain the age‐dependent decline in the delayed memory for it. There was no significant age‐effect for delayed memory of the explicit Hebb sequence, with both age groups showing retention. Overall performance by adults was positively correlated with measures of post‐learning awareness. Performance by children was positively correlated with vocabulary knowledge. We conclude that children outperform adults in the retention over time of implicitly learned phonological sequences that will gradually consolidate into novel word‐forms. The findings are discussed in the light of maturational differences for implicit versus explicit memory systems that also play a role in language acquisition.

Unfamiliar face matching is a surprisingly difficult task, yet we often rely on people's matching decisions in applied settings (e.g., border control). Most attempts to improve accuracy (including training and image manipulation) have had very limited success. In a series of studies, we demonstrate that using smiling rather than neutral pairs of images brings about significant improvements in face matching accuracy. This is true for both match and mismatch trials, implying that the information provided through a smile helps us detect images of the same identity as well as distinguishing between images of different identities. Study 1 compares matching performance when images in the face pair display either an open-mouth smile or a neutral expression. In Study 2, we add an intermediate level, closed-mouth smile, to identify the effect of teeth being exposed, and Study 3 explores face matching accuracy when only information about the lower part of the face is available. Results demonstrate that an open-mouth smile changes the face in an idiosyncratic way which aids face matching decisions. Such findings have practical implications for matching in the applied context where we typically use neutral images to represent ourselves in official documents. 相似文献

Despite a continued focus exploring the factors related to plagiarism, the relationship between English language ability and plagiarism occurrences is not fully understood. Multiple studies involving student or faculty self-reporting of plagiarism have shown that students often claim English language ability is one of the main reasons why they commit plagiarism offences; however, little research has tested these claims in a rigorous, quantitative manner. This paper presents the findings of an analysis of data collected in a private, international university located in Vietnam, from non-native English speaking students studying business degrees. Analysis of the data builds on previous studies by showing that there are statistically significant differences in the English language abilities of students who have previously committed plagiarism offences, compared to students who have not, suggesting that programmes designed to improve the academic English skills of non-native English speaking students may help reduce incidences of plagiarism. 相似文献

A model for teaching children skills to strengthen emotional self-regulation is introduced, informed by the developmental
concept of scaffolding. Adult modeling/instruction, role-play and in vivo coaching are tailored to children’s level of understanding
and skill to promote use of skills in reallife contexts. Two-hundred twenty-six kindergarten—3rd grade children identified
with elevated behavioral and social classroom problems from a population-based screening participated in a waitlisted randomized
trial of the Rochester Resilience Project derived from this model. In 14 lessons with school-based mentors, children were
taught a hierarchical set of skills: monitoring of emotions; selfcontrol/ reducing escalation of emotions; and maintaining
control and regaining equilibrium. Mentors provided classroom reinforcement of skill use. Multi-level modeling accounting
for the nesting of children in schools and classrooms showed the following effects at post-intervention: reduced problems
rated by teachers in behavior control, peer social skills, shy-withdrawn and off-task behaviors (ES 0.31–0.47). Peer social
skills improved for girls but not for boys. Children receiving the intervention had a 46% mean decrease in disciplinary referrals
and a 43% decrease in suspensions during the 4-month intervention period. Limitations and future directions to promote skill
transfer are discussed. 相似文献

The assessment of cognitive function in individuals of culturally and linguistically diverse background poses considerable challenges for the psychologist, particularly when English proficiency is limited. This study explored the effects of diverse cultural background and non‐Western educational background on Wechsler Adult Intelligence Scale‐Third edition (WAIS‐III) and Wechsler Memory Scale‐Third Edition (WMS‐III) performances in moderate‐severe traumatic brain injury within an outpatient rehabilitation setting. Participants were aged 16–65 years and met careful selection criteria. IQ, index and age‐scaled subtest scores were compared across three groups: (a) English‐speaking background (n = 130), (b) culturally and linguistically diverse background and education completed in English (n = 33), and (c) culturally and linguistically diverse background and non‐English education (n = 33). Cultural backgrounds included people of Asian, European, Middle Eastern, African and Oceania origin. Results were that the English‐educated culturally and linguistically diverse group performed lower than the English‐speaking background group on some verbal WAIS‐III measures; effect sizes were small‐moderate. The non‐English‐educated culturally and linguistically diverse group performed lower than both groups on several WAIS‐III and one WMS‐III measure, with large effect sizes. Clinical implications included the need for caution in interpreting test scores to avoid diagnostic errors and the need for further development of valid assessment tools. 相似文献

Current cognitive models stress the importance of negative self-perceptions in maintaining social anxiety, but focus predominantly on content rather than structure. Two studies examine the role of self-structure (self-organisation, self-complexity, and self-concept clarity) in social anxiety. In study one, self-organisation and self-concept clarity were correlated with social anxiety, and a step-wise multiple regression showed that after controlling for depression and self-esteem, which explained 35% of the variance in social anxiety scores, self-concept clarity uniquely predicted social anxiety and accounted for an additional 7% of the variance in social anxiety scores in an undergraduate sample (N = 95) and the interaction between self-concept clarity and compartmentalisation (an aspect of evaluative self-organisation) at step 3 of the multiple regression accounted for a further 3% of the variance in social anxiety scores. In study two, high (n = 26) socially anxious participants demonstrated less self-concept clarity than low socially anxious participants (n = 26) on both self-report (used in study one) and on computerised measures of self-consistency and confidence in self-related judgments. The high socially anxious group had more compartmentalised self-organisation than the low anxious group, but there were no differences between the two groups on any of the other measures of self-organisation. Self-complexity did not contribute to social anxiety in either study, although this may have been due to the absence of a stressor. Overall, the results suggest that self-structure has a potentially important role in understanding social anxiety and that self-concept clarity and other aspects of self-structure such as compartmentalisation interact with each other and could be potential maintaining factors in social anxiety. Cognitive therapy for social phobia might influence self-structure, and understanding the role of structural variables in maintenance and treatment could eventually help to improve treatment outcome. 相似文献

Temperament and personality traits constitute inherent and learned personal characteristics that are crucial for creative behaviors among high ability students. This study investigated the relationships of temperament dimensions and the Big Five personality traits to creativity among 406 honors college students. First, the associations of creativity with temperament and personality were investigated separately. Second, it was sought to document if the selected measures of personality and temperament are distinguishable despite their interdependence. Finally, a mediational role for personality traits in channeling the effect of temperament on creativity was hypothesized. In the mediation model, all four temperament dimensions (orienting sensitivity, effortful control, extraversion/surgency, negative affect) had direct or indirect relationships with creativity. Two personality traits (openness, neuroticism) were found to be significant mediators in these relationships. The findings were discussed in terms of their relevance to the high-ability college students and to the temperament, personality, and creativity literature in general. 相似文献
