The effect of aging on the memory enhancement of the survival judgment task

This study investigated whether or not aging affected the benefit of a survival judgment task. Sixteen young adults and 16 older adults participated in this experiment. In the survival task, participants were requested to judge whether a word was necessary or not in a survival situation. In the self‐referent judgment task, participants were requested to judge how easily the word brings to mind an important personal experience. Participants in each condition were presented 18 concrete nouns at 4‐s intervals. Our results showed that even though the survival judgment task enhanced the memory performance in both the young adults and the older adults, the young adults outperformed the older adults in the survival and self‐referent judgment tasks.     

Can the memory enhancement of the survival judgment task be explained by the elaboration hypothesis?: Evidence from a memory load paradigm1

Many reports have described a survival judgment task that requires participants to judge words according to their relevance to a survival situation, eliciting better recall than that obtained in other judgment tasks (e.g., semantic or self‐judgment tasks). Two explanatory hypotheses (the adaptive hypothesis and the elaboration hypothesis) have been proposed. Here we used the memory load paradigm to investigate whether the adaptive hypothesis or the combination hypothesis can better account for the memory enhancement of the survival judgment task. We used a survival judgment task and an autobiographical recall task with the condition of no memory load or memory load. The 48 participants performed four encoding conditions (memory load—survival, no memory load—survival, memory load—autobiographical, and no memory load—autobiographical). The results showed that memory enhancement of the survival judgment task occurred only in the no memory load condition, but not in the memory load condition. Our results support the elaboration hypothesis. We also discuss the validity of the elaboration hypothesis and future directions to be pursued in this research field.     

Influence of subjective difficulty on the degree of configural and featural processing in face recognition1

This study aimed to assess the effect of subjective difficulty on the degree of featural or configural processing in face recognition. It could be assumed that featural processing is analytic processing ( Peterson & Rhodes, 2003 ), while configural processing is automatic processing ( Dunning & Stern, 1994 ). It has been suggested that task difficulty affected the automaticity of processing. Task difficulty was manipulated using a number of alternatives or time pressure. Subjective difficulty could also affect the automaticity of processing. If so, then subjective difficulty may in turn affect the degree of featural or configural processing. Participants in a difficult condition were given instructions mentioning that the face‐recognition task was difficult, while participants in the control condition were given no such instruction. The amount of retrieved featural information in the former condition was less than that in the latter. These results suggested that the degree of featural processing decreased when the participants found the task difficult.     

体像困扰与社会文化因素

数据显示大多数人对自己的体像不满意,而对体像的不满意可能形成困扰。存在体像困扰的个体更多体验抑郁、焦虑等负面情绪,且体像困扰和进食障碍、体像障碍等精神疾病均存在密切的关系。在介绍概念的同时,本文还对体像困扰相关社会文化因素的影响进行了综述。已有研究表明女性较男性更容易受到体像困扰的影响;体像困扰存在跨文化的一致性,也存在文化差异;家庭、同伴和媒体对于体像困扰均有影响。

Individual differences of visual imagery ability in the benefit of a survival judgment task

This study investigated whether or not visual imagery ability affected the benefit of a survival judgment task. Based on the median split of their VVIQ score, 92 undergraduate students were classified as either high imagers (n = 46) or low imagers (n = 46). In the survival task, participants were requested to judge whether an item presented in the form of two Chinese characters was necessary or not in a survival situation. In the image judgment task, participants were requested to judge whether an item presented in the form of two Chinese characters arouses mental images or not. Participants were presented 18 concrete nouns at 4 s intervals in each condition. In both the survival judgment and the image judgment tasks, high imagers recalled more words than low imagers did. This result showed that imagery ability influenced the benefit of the survival judgment task. These results were discussed from the functional perspective of memory. Finally, we proposed the combination hypothesis, which combined elaboration and functional perspectives to explain the benefit of the survival judgment task.
