寂寞身后事,蓄势待来年——让·皮亚杰(J.Piaget)逝世30周年祭

皮亚杰逝世已30年,但皮亚杰所创立的发生认识论研究不应走向历史。皮亚杰的理论遭到许多人的误解。遗传论和生物学化是两项最为不恰当的帽子。皮亚杰不是传统意义上的心理学家,心理学只是其研究康德意义上的"先验范畴"之个体发生发展的"方法论插曲"。发生认识论具有鲜明的跨学科性质,应该进行"发生认识论"与当代"认知科学"的比较研究。应正确认识理论生物学、结构主义方法论、代数工具和逻辑学在发生认识论研究中的作用和地位,尤其应注重晚年皮亚杰运用新的意义逻辑(logic of meaning)和态射(morphisms)、范畴(categories)等新的代数概念作为形式化认知结构之工具的价值和意义。要深入研究发生认识论对以"具身化"和"回归大脑"为特色的第二代认知科学的启示,探讨它们之间的联系。至少在两个方面可以明显看到这种联系:一是发生认识论中的"动作协调"及对由协调而产生的逻辑—数学经验的"反省抽象"这两个概念,表明了皮亚杰对心智具身性的卓越洞见;二是在皮亚杰所主张的"表型复制"(phynocopy)观点中体现的衍生论(epigenesis)和建构论(constructionism)思想,它们与第二代认知科学的动力系统理论之基本思想——所涉因素或变量之间的关系是一种互为因果、相互塑造的对偶(coupling)关系而不是线性的单向因果关系——两者是完全一致的。皮亚杰及其发生认识论定会随着认知科学的未来发展而被"再发现"。     

Health anxiety,anxiety sensitivity,and attentional biases for pictorial and linguistic health‐threat cues

The study investigated attentional biases for pictorial and linguistic health‐threat stimuli in high and low health anxious individuals, who were selected from the upper and lower quartile ranges of a normal sample using a screening measure of health anxiety. Attentional bias was assessed using a visual probe task which presented health‐threat and neutral pictures and words at two exposure durations, 500 ms and 1250 ms. The prediction that the high health anxious group would show a greater attentional bias for health‐threat cues than the low health anxious group was not supported despite the groups being well‐differentiated on a general measure of health anxiety, the Illness Attitudes Scale (IAS). Instead, the results indicated that individuals with high levels of anxiety sensitivity showed a significantly greater initial attentional bias for threat pictures compared with those with low anxiety sensitivity, as assessed by the Anxiety Sensitivity Index (ASI).     

Intact emotion–cognition interaction in schizophrenia patients and first-degree relatives: Evidence from an emotional antisaccade task

Schizophrenia patients have deficits in cognitive control as well as in a number of emotional domains. The antisaccade task is a measure of cognitive control that requires the inhibition of a reflex-like eye movement to a peripheral stimulus. Antisaccade performance has been shown to be modulated by the emotional content of the peripheral stimuli, with emotional stimuli leading to higher error rates than neutral stimuli, reflecting an implicit emotion processing effect. The aim of the present study was to investigate the impact on antisaccade performance of threat-related emotional facial stimuli in schizophrenia patients, first-degree relatives of schizophrenia patients and healthy controls. Fifteen patients, 22 relatives and 26 controls, matched for gender, age and verbal intelligence, carried out an antisaccade task with pictures of faces displaying disgusted, fearful and neutral expressions as peripheral stimuli. We observed higher antisaccade error rates in schizophrenia patients compared to first-degree relatives and controls. Relatives and controls did not differ significantly from each other. Antisaccade error rate was influenced by the emotional nature of the stimuli: participants had higher antisaccade error rates in response to fearful faces compared to neutral and disgusted faces. As this emotional influence on cognitive control did not differ between groups we conclude that implicit processing of emotional faces is intact in patients with schizophrenia and those at risk for the illness.     

Time-Out for Sibling Aggression: An Analysis of Effective Durations in a Natural Setting

Abstract

Time-out is a ubiquitous strategy to reduce problem behaviors. The current study sought to find the shortest effective duration(s) of time-out for sibling aggression in a community sample of girls ages 3–7. All participants reached a minimum reduction in sibling aggression of 60% after experiencing a 1-minute time-out. The majority (75%) of participants also demonstrated clear reversals of behavior when returned to the baseline condition. The current findings suggest that a 1-minute time-out may be sufficient for low-level sibling aggression in children as old as seven. Limitations include the presence of a graduate assistant during sibling play and unclear generalizability.     

Effects of Interpretation Training on Hostile Attribution Bias and Reactivity to Interpersonal Insult

Research suggests that individuals high in anger have a bias for attributing hostile intentions to ambiguous situations. The current study tested whether this interpretation bias can be altered to influence anger reactivity to an interpersonal insult using a single-session cognitive bias modification program. One hundred thirty-five undergraduate students were randomized to receive positive training, negative training, or a control condition. Anger reactivity to insult was then assessed. Positive training led to significantly greater increases in positive interpretation bias relative to the negative group, though these increases were only marginally greater than the control group. Negative training led to increased negative interpretation bias relative to other groups. During the insult, participants in the positive condition reported less anger than those in the control condition. Observers rated participants in the positive condition as less irritated than those in the negative condition and more amused than the other two conditions. Though mediation of effects via bias modification was not demonstrated, among the positive condition posttraining interpretation bias was correlated with self-reported anger, suggesting that positive training reduced anger reactivity by influencing interpretation biases. Findings suggest that positive interpretation training may be a promising treatment for reducing anger. However, the current study was conducted with a non-treatment-seeking student sample; further research with a treatment-seeking sample with problematic anger is necessary.     

Cognitive bias modification of interpretations: A viable treatment for child and adolescent anxiety?

Anxiety disorders in children and adolescents are common and impairing. As many patients do not benefit from – or have difficulties accessing – frontline treatments, novel, effective and easy-to-deliver interventions are needed. Cognitive Bias Modification of Interpretations (CBM-I) training has been used to treat adult anxiety disorders. CBM-I methods train individuals to endorse benign rather than negative resolutions of ambiguous cues. Developmental extensions of CBM-I are important for several reasons. First, implementing CBM-I in symptomatic children and adolescents may facilitate early preventative gains. Second, as training uses simple learning mechanisms, CBM-I may reflect a developmentally-suitable strategy for shaping adaptive processing styles. Third, as this age range involves protracted neurocognitive maturation and associated plasticity, administering CBM-I early could drive powerful, long-lasting benefits for emotional development. Finally, data from CBM-I studies could inform the cognitive mechanisms involved in the genesis of early-emerging anxiety. This paper provides the first organised review of CBM-I studies conducted in children and adolescents, and contains suggestions for future research that may help realise the therapeutic potential of early CBM-I interventions.     

Understanding responses to predictive genetic testing: A grounded theory approach

Abstract

In view of the absence of data concerning the understanding and experience of families in which one or more members have undergone predictive genetic testing, a pilot study using a qualitative methodology was conducted with members of families at risk for the late-onset genetic disease, familial adenomatous polyposis (FAP). Semistructured interviews were conducted to elicit illness representations, with responses tape-recorded and analysed using a grounded theory approach. Several themes emerged. The most striking was that when genetic testing indicated an extremely low risk of developing the disease, there was a desire to continue regular bowel screening, even though it was experienced as extremely aversive. Possible explanations draw upon both other themes of the interviews, and psychological models. The role of “functional pessimism” and “uncertain wellness” in maintaining a high threat from the disease, and the role of reinforcement and the nature of tests in providing bowel screening with a high value are discussed.     

A genetic variant (COMT) coding dopaminergic activity predicts personality traits in healthy elderly

Association studies between the NEO five factor personality inventory and COMT rs4680 have focused on young adults and the results have been inconsistent. However, personality and cortical changes with age may put older adults in a more sensitive range for detecting a relationship. The present study examined associations of COMT rs4680 and personality in older adults.Genetic association analyses were carried out between the NEO and the targeted COMT rs4680 in a large, well-characterized sample of healthy, cognitively normal older adults (N = 616, mean age = 69.26 years).Three significant associations were found: participants with GG genotype showed lower mean scores on Neuroticism (p = 0.039) and higher scores on Agreeableness (p = 0.020) and Conscientiousness (p = 0.006) than participants with AA or AG genotypes.These results suggest that older adults with higher COMT enzymatic activity (GG), therefore lower dopamine level, have lower Neuroticism scores, and higher Agreeableness and Conscientiousness scores. This is consistent with a recent model of phasic and tonic dopamine release suggesting that even though GG genotype is associated with lower tonic dopamine release, the phasic release of dopamine might be optimal for a more adaptive personality profile.     

Body Modification Sites and Abuse History

Self-reported experience of physical, sexual, and mental abuse and general emotional abandonment was significantly associated with a variety of piercings, tattoos, and scarifications in a sample of 4,700 members of an online body-modification site. More significant associations were found for the women in the sample than for the men. Possible clinical implications of the results are discussed.     

Classification of dog barks: a machine learning approach

In this study we analyzed the possible context-specific and individual-specific features of dog barks using a new machine-learning algorithm. A pool containing more than 6,000 barks, which were recorded in six different communicative situations was used as the sound sample. The algorithm's task was to learn which acoustic features of the barks, which were recorded in different contexts and from different individuals, could be distinguished from another. The program conducted this task by analyzing barks emitted in previously identified contexts by identified dogs. After the best feature set had been obtained (with which the highest identification rate was achieved), the efficiency of the algorithm was tested in a classification task in which unknown barks were analyzed. The recognition rates we found were highly above chance level: the algorithm could categorize the barks according to their recorded situation with an efficiency of 43% and with an efficiency of 52% of the barking individuals. These findings suggest that dog barks have context-specific and individual-specific acoustic features. In our opinion, this machine learning method may provide an efficient tool for analyzing acoustic data in various behavioral studies.
