概括
为任务做准备会激活其表示,因此需要抑制以后的切换. 这项研究表明,任务提示的准备,而不仅仅是执行,可以触发抑制,特别是在实验的早期和与相容的提示.
科学领域:
- 认知心理学 认知心理学
- 神经科学是一个神经科学.
- 人类表现的人类表现.
背景情况:
- 任务切换包括通过激活任务集来准备即将到来的任务.
- 讨论了准备在任务集抑制中的作用,特别是n-2重复成本.
- 了解任务集抑制对于解释任务变化期间的认知控制至关重要.
研究的目的:
- 调查仅仅为任务做准备 (通过线索) 是否激活了需要抑制的任务集.
- 检查n-2重复成本的出现,作为提示诱导的任务集抑制的指数.
- 要区分抑制准备与执行任务集的抑制.
主要方法:
- 在n-2间隔中使用任务提示单独试验的两个实验.
- 评估n-2的重复成本后的任务提示,只与任务执行.
- 对提示任务兼容性和实验实践的操纵.
主要成果:
- 在只进行任务提示的试验后,观察到N-2重复成本,但仅适用于兼容的提示和实验的早期.
- 在n-2试验中,任务执行后没有N-2重复成本.
- 这些发现被复制,表明提示诱导的任务集抑制取决于兼容性和实践.
结论:

Feedback Inhibition
Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!
Obedience
According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation, obedience...
Persuasion Strategies
Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).
Social Loafing
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated, individuals become less...
Tip-of-the-Tongue Phenomenon
The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...
Impression Management Techniques III: Aligning Actions
Aligning actions are communicative strategies individuals employ to maintain social harmony and preserve personal identity in the face of potential disruptions to social norms. These actions are particularly important in managing social impressions when one's behavior might be seen as inappropriate, incompetent, or morally questionable.Types of Aligning ActionsThe three principal types of aligning actions are disclaimers, accounts, and apologies.DisclaimersDisclaimers are preventive; they are...
