Response time modeling reveals multiple contextual cuing mechanisms

Contextual cuing refers to a response time (RT) benefit that occurs when observers search through displays that have been repeated over the course of an experiment. Although it is generally agreed that contextual cuing arises via an associative learning mechanism, there is uncertainty about the type(s) of process(es) that allow learning to influence RT. We contrast two leading accounts of the contextual cuing effect that differ in terms of the general process that is credited with producing the effect. The first, the expedited search account, attributes the cuing effect to an increase in the speed with which the target is acquired. The second, the decision threshold account, attributes the cuing effect to a reduction in the response threshold used by observers when making a subsequent decision about the target (e.g., judging its orientation). We use the diffusion model to contrast the quantitative predictions of these two accounts at the level of individual observers. Our use of the diffusion model allows us to also explore a novel decision-level locus of the cuing effect based on perceptual learning. This novel account attributes the RT benefit to a perceptual learning process that increases the quality of information used to drive the decision process. Our results reveal both individual differences in the process(es) involved in contextual cuing but also identify several striking regularities across observers. We find strong support for both the decision threshold account as well as the novel perceptual learning account. We find relatively weak support for the expedited search account.     

On the validity of remember-know judgments: evidence from think aloud protocols

The use of remember–know judgments to assess subjective experience associated with memory retrieval, or as measures of recollection and familiarity processes, has been controversial. In the current study we had participants think aloud during study and provide verbal reports at test for remember–know and confidence (i.e., sure–probably) judgments. Results indicated that the vast majority of remember judgments for studied items were associated with recollection from study (87%), but this correspondence was less likely for high-confidence judgments (72%). Instead, high-confidence judgments were more likely than remember judgments to be associated with incorrect recollection and a lack of recollection. Know judgments were typically associated with a lack of recollection (62%), but still included recollection from the study context (33%). Thus, although remember judgments provided fairly accurate assessments of retrieval including contextual details, know judgments did not provide accurate assessments of retrieval lacking contextual details.     

Autonomy and moral deference

The idea that a person might have a duty to defer to the moral judgments of others is typically something that arouses our suspicion, in ways that other kinds of deference do not. One explanation for this is the value of autonomy. According to this explanation, people have a duty to be autonomous, and any act of deferring to another person’s moral judgement is not an autonomous action. Call this “the Autonomy Argument” against moral deference. In this article, I criticise the Autonomy Argument. I argue that, even if we accept that an act of moral deference can never be autonomous, those who believe that people have a duty to be autonomous must accept that acts of moral deference are morally necessary. This is because some people are incapable of becoming autonomous by themselves, and deferring to a moral expert is the only way they might ever become autonomous.     

Manipulated stress and dispositional reinvestment in a wall-volley task: an investigation into controlled processing

This field-based study examined the action of reinvesting in controlled processing on 14 university soccer players to assess skill breakdown under pressure. Based on scores on the Reinvestment Scale of Masters, Polman, and Hammond, two experimental groups of participants were inferred to be dispositionally High or Low in Reinvestment. They performed a wall-volley soccer task, which involved kicking a ball repeatedly against a wall target zone for 90 sec. as defined by McMorris, Gibbs, Palmer, Payne, and Torpey in a High and Low Stress environment. Prior to each condition performers were required to complete the Anxiety Rating Scale. A series of two-way (reinvestment x stress) analyses of variance with repeated measures on stress were conducted on the Anxiety and soccer scores. Players scoring High on the Reinvestment Scale reported significantly greater Intensity for Somatic Anxiety and lower Self-confidence than players who scored Low in the High Stress condition. Anxiety Direction scores indicated players scoring High on the Reinvestment Scale reported their increase in Somatic Anxiety and reduction in Self-confidence in the High Stress condition to be significantly more debilitating of performance than players who scored Low on the Reinvestment Scale. Soccer scores indicated players scoring High on the Reinvestment Scale were more prone to reinvesting in controlled processing and essentially experiencing greater decreases in performance under pressure than those Low in Reinvestment. Therefore, these findings support the predictive power of the Reinvestment Scale.     

Frames of reference and cooperative social decision-making

Cooperative decision-making was studied as a function of the decision-makers' own, and the interdependent other party's gain or loss frame. As expected, results showed that (a) an own gain frame produced less cognitive activity than an own loss frame and (b) other's loss frame caused more cooperation than other's gain frame, but only in case of an own gain frame.     

A CRITIQUE OF FREGE ON COMMON NOUNS

Frege analyzed the grammatical subject‐term ‘S’ in quantified subject‐predicate sentences, ‘q S are P’, as being logically predicative. This is in contrast to Aristotelian Logic, according to which it is a logical subject‐term, like the proper name ‘a’ in ‘a is P’– albeit a plural one, designating many particulars. I show that Frege’s arguments for his analysis are unsound, and explain how he was misled to his position by the mathematical concept of function. If common nouns in this grammatical subject position are indeed logical subject‐terms, this should require a thorough reevaluation of the adequacy of Frege’s predicate calculus as a tool for the analysis of the logic and semantics of natural language.     

Predictors of Premature Match Closure in Youth Mentoring Relationships

Although mentoring is a popular and effective means of intervention with youth, the positive effects of mentoring can be diminished by premature match closure of relationships. Program, mentor, and mentee characteristics were examined as predictors of premature match closure. Secondary data analyses were conducted on a large national database of mentoring programs consisting of match and youth risk information from 170 mentoring programs and 6468 matches from across the U.S. Premature closure was associated with mentee age at match inception and 19 individual mentee characteristics. The set of mentee characteristics were examined as part of a cumulative risk index encompassing seven conceptually combined categories including family background characteristics, school functioning problems, engagement in risky health behaviors, self‐regulation difficulties, engagement in illegal or criminal activities, and internalizing and externalizing behavior problems. Both the age of mentees when matched and the cumulative risk index score significantly predicted premature closure. Results are discussed in terms of directions for future research and suggestions for enhancing mentoring program practices.     

Determinants of depressive mood states in everyday life: An experience sampling study

This study tests relative contributions and time-course of proposed risk/protective factors (e.g., stress, coping, and lack of social interactions) for influencing depressed mood states in daily life. Seventy-three participants completed baseline measurement of major depressive disorder symptomatology, followed by smartphone app-based monitoring of momentary experiences of depressed mood and risk/protective factors for 7 days. All predictors had deteriorating impacts on mood as lag increased, and the optimal lag appears to be less than 120 min. Linear decay in effect sizes was found for physical activity, social interaction, and tiredness, whereas exponential decline in effect sizes was found for stress and coping ability. Stress, coping, and depressed mood at the prior time-point were the best predictors of subsequent mood. These effects did not differ as a function of trait depressive symptom severity. Findings highlight the influence of spacing of assessments in identification and magnitude of predictors of mood states, and provide insights into key drivers of change in mood and their time-course.
