Confession evidence,psychological vulnerability and expert testimony

There have been major changes in English Law with regard to confession evidence, which followed the implementation of the Police and Criminal Evidence Act (PACE) in January 1986. This paper reviews the main legal changes that are relevant to the admissibility and reliability of confessions and their psychological importance within the context of both research and expert testimony.     

经验、材料性质及加工水平对虚假记忆的影响

本实验采用DRM研究范式,考察经验、材料性质和加工水平三个方面对虚假记忆的影响。实验首次采用句子的方式呈现,给被试提供符合经验和不符合经验的句子进行学习和再认。实验结果显示,三个因素对虚假记忆的影响都是显著的,其中,经验是导致虚假记忆产生的主导因素,加工深度同经验之间以及材料性质同经验之间的交互作用均存在显著的交互作用。     

5～8岁儿童对模糊信息具有多重解释的理解

参照Carpendale和Chandler的实验范式,研究儿童对于“人们可能对同样信息给出不同解释”这一现象的理解,考察5~8岁儿童的解释性心理理论的发展。结果表明,5岁儿童不能理解心理过程的解释性,认为同样的信息只有一种合理的解释。从6岁开始,儿童才认识到,模糊信息可以有多种解释,但6、7岁时的这种理解并不完善,成绩随着任务要求而变化。8岁儿童才有比较稳定的解释性心理理论。     

Regional brain activity change predicts responsiveness to treatment for stuttering in adults

Developmental stuttering is known to be associated with aberrant brain activity, but there is no evidence that this knowledge has benefited stuttering treatment. This study investigated whether brain activity could predict progress during stuttering treatment for 21 dextral adults who stutter (AWS). They received one of two treatment programs that included periodic H₂¹⁵O PET scanning (during oral reading, monologue, and eyes-closed rest conditions). All participants successfully completed an initial treatment phase and then entered a phase designed to transfer treatment gains; 9/21 failed to complete this latter phase. The 12 pass and 9 fail participants were similar on speech and neural system variables before treatment, and similar in speech performance after the initial phase of their treatment. At the end of the initial treatment phase, however, decreased activation within a single region, L. putamen, in all 3 scanning conditions was highly predictive of successful treatment progress.     

False memories in obstructive sleep apnoea syndrome: evidence from the divided attention paradigm at encoding or retrieval

ABSTRACT

Patients with obstructive sleep apnoea syndrome (OSAS) exhibit impaired retrieval of item-specific information, increasing their propensity to generate false recognitions. The present study investigated the effect of OSAS on false recognition, using a divided-attention paradigm to examine whether reducing the availability of attentional resources during encoding or retrieval in healthy participants mimics the effect of OSAS. We tested four groups of participants, using the Deese – Roediger – McDermott paradigm: patients with OSAS and controls, either under full attention or under divided attention at encoding or retrieval. Results showed that divided attention at retrieval, but not at encoding, mimicked the effects of OSAS on memory performance, as controls in this group exhibited a higher level of false recognition than those under full attention, but a similar level of correct recognition. Our results suggest that the greater susceptibility of patients with OSAS to false recognition may be due to a limited availability of attentional resources, which may specifically disrupt retrieval processes.     

The Roles of Explanation and Feedback in False Belief Understanding: A Microgenetic Analysis

The authors examined effects of feedback and explanation on false belief performance. Thirty-three children (42–54 months; 15 girls, 18 boys) were randomly assigned to four treatment conditions: explanation, feedback, feedback researcher explains, and feedback child explains. Children completed false belief tasks during pretraining, 8 training sessions, and posttraining across 6 weeks. Language comprehension was assessed at pretraining. The authors hypothesized that children would improve most when training involved feedback and explanation. Generalized estimating equations modeling was used to analyze the data. Children who received feedback and generated explanations for characters’ false beliefs improved across training sessions more so than children in other conditions. Children's explanations for false beliefs also were explored. Implications of the findings are discussed.
