Natural Compatibilism,Indeterminism, and Intrusive Metaphysics

The claim that common sense regards free will and moral responsibility as compatible with determinism has played a central role in both analytic and experimental philosophy. In this paper, we show that evidence in favor of this “natural compatibilism” is undermined by the role that indeterministic metaphysical views play in how people construe deterministic scenarios. To demonstrate this, we re-examine two classic studies that have been used to support natural compatibilism. We find that although people give apparently compatibilist responses, this is largely explained by the fact that people import an indeterministic metaphysics into deterministic scenarios when making judgments about freedom and responsibility. We conclude that judgments based on these scenarios are not reliable evidence for natural compatibilism.     

Differentiated perceptions of exertion: part II. relationship to local and central physiological responses

Differentiated ratings of perceived exertion in the legs and chest were compared to local and central physiological adjustments during submaximal cycle ergometer exercise. 50 male subjects performed three separate cycle ergometer tests. Power output was held constant at 840 kpm/min., while pedalling rate was randomly set at 40, 60, or 80 rpm. Differentiated reports of exertion from the legs were considered to be local signals and reports from the chest to be central signals. Ratings of exertion for the legs, chest and over-all body were each significantly higher at 40 rpm than 60 or 80 rpm. Heart rate, oxygen uptake, ventilation and respiratory rate were also higher at 40 rpm. Lactic acid, pH, and pCO2 were similar between pedalling rates. Lactic acid did not operate differentially to influence local perceptual signals from the legs. Central measures of respiratory and aerobic metabolic adjustments were consistent with the more intense regional report of chest exertion at 40 rpm.     

Agonistic rank,aggression, social context,and testosterone in male pigtail monkeys

Two groups of pigtail monkeys were merged, a third was formed, and individual males were introduced into a group in a series of experiments examining the effects of social context upon agonistic rank, aggressive expression, and testosterone levels. In the first experiment, two heterosexual groups, containing adult males unfamiliar to the other group, were merged. The two groups fought, and the smaller group was defeated. The alpha and beta males of the defeated group were singled out for repeated attack and both showed significant drops in circulating levels of testosterone. Both males were removed from the group during the first day, but testosterone levels did not recover to baseline levels for several days. The alpha male of the victorious group, on the other hand, showed a significant rise in testosterone, which was apparent only on the day following the merger. In order to study the influence of previous social familiarity on male reception into a group, another group was formed by removing males from the victorious group and placing them in a separate enclosure. The males in the new group established a dominance hierarchy unrelated to their previous social ranks with one another. Three months later, each of the six adult males remaining in the parent group was individually introduced into the new group for one day or less. Each of the males introduced into the new group accepted a social position at the lower end of the dominance hierarchy without regard to his previous rank relationships with the host males when they were all in the parent group. Even the alpha and beta males of the parent group were relegated to low rank positions in the new group, despite having ranked over each of the host males since birth. In contrast to the aggression directed at the unfamiliar males in the first experiment, a minimum of aggression was directed to the familiar males introduced into the new group in the second experiment. Although the males introduced accepted low social ranks, it appeared that each was readily integrated into the group with a minimum of aggressive interaction during the time he was scheduled to remain in the group. There were no significant changes in circulating levels of testosterone in any of the males during the introductions of familiar males to one another.     

Mentors' perceptions of negative mentoring experiences: scale development and nomological validation

Three studies were conducted to develop a psychometrically sound, multidimensional measure of mentors' perceptions of negative experiences with their protégés. In Study 1, items were developed, and content-related validity was established. In Study 2, CFA was used to establish the dimensionality of the new measure. Construct-related (convergent and discriminant) and criterion-related validity evidence were also obtained by using data from matched mentor-protégé dyads. Study 3 replicated the factor structure of the instrument and provided additional validity evidence by using a sample of female academic mentors. The findings are discussed in terms of broadening the scope of mentoring research to consider the mentor's perspective of relationship problems and dyadic processes in mentoring relationships.     

The "cost of caring" in youths' friendships: considering associations among social perspective taking, co-rumination, and empathetic distress

The current research considered the costs of caring in youths' friendships. The development of a new construct, empathetic distress, allowed for a direct test of the commonly held belief that females suffer greater vicarious distress in response to close others' stressors and problems than do males. Empathetic distress refers to one's strongly sharing a relationship partner's distress over problems to the point of taking on the partner's distress and experiencing it as one's own. This new construct was examined in an ethnically diverse sample of early adolescents who responded to a series of questionnaires in their classrooms. Results indicated that girls did experience greater empathetic distress in friendships than did boys. In addition, the current research revealed that social perspective taking in friendships (i.e., the social-cognitive ability to infer and understand the friend's perspective) had adjustment trade-offs in that it predicted greater positive friendship quality but also greater empathetic distress in the friendship. Interestingly, the associations of social perspective taking with both positive friendship quality and empathetic distress were partially mediated by co-rumination or excessive discussion of problems. Applied implications of the findings that girls' greater social perspective taking and associated co-rumination contributed both to their greater positive friendship quality but also to greater costs of caring in the form of empathetic distress are discussed.     

Alcohol Intoxication and Metamemory: Little Evidence that Moderate Intoxication Impairs Metacognitive Monitoring Processes

There is minimal research on metacognition in alcohol‐intoxicated participants. Study 1 examined metacognition across sober, intoxicated, and placebo groups, with the intoxicated group's breath alcohol concentration reaching 0.074 g/210 L on average immediately prior to the metacognition task. Participants answered cued recall general knowledge questions and provided confidence ratings and feeling‐of‐knowing judgments. They then completed a recognition (i.e., multiple choice) version of the same task, indicating an answer and a confidence rating for each question. Findings suggest that metacognitive accuracy generally did not vary across intoxication levels, although the control group's retrospective confidence judgments better discriminated between accurate and inaccurate responses than the alcohol groups in the recognition task. Study 2 surveyed academic psychologists about their expectations regarding the relation between alcohol and metacognition. Study 1's results were counter to their expectations, as respondents generally predicted a relation would be present. We discuss the implications for alcohol and memory.Copyright © 2017 John Wiley & Sons, Ltd.     

Benefits from retrieval practice are greater for students with lower working memory capacity

We examined the effects of retrieval practice for students who varied in working memory capacity as a function of the lag between study of material and its initial test, whether or not feedback was given after the test, and the retention interval of the final test. We sought to determine whether a blend of these conditions exists that maximises benefits from retrieval practice for lower and higher working memory capacity students. College students learned general knowledge facts and then restudied the facts or were tested on them (with or without feedback) at lags of 0–9 intervening items. Final cued recall performance was better for tested items than for restudied items after both 10 minutes and 2 days, particularly for longer study–test lags. Furthermore, on the 2-day delayed test the benefits from retrieval practice with feedback were significantly greater for students with lower working memory capacity than for students with higher working memory capacity (r?=??.42). Retrieval practice may be an especially effective learning strategy for lower ability students.     

Post hoc versus predictive accounts of children’s theory of mind: A reply to Ruffman

Ruffman (2014) argues for a minimalist account of infants’ performance on theory of mind tasks. This commentary argues that because Ruffman’s minimalist account is post hoc, it neither generates testable predictions about how infants will respond in new situations, nor does it offer a coherent explanation for existing false-belief findings. An alternative, mentalist account is presented. This account integrates infancy findings with prior theory of mind literature and generates novel predictions about children’s false belief performance.     

Aptitude and Trait Predictors of Manned and Unmanned Aircraft Pilot Job Performance

Sixty-seven United States Navy maintainers (55 men and 12 women) representing both the aviation and surface communities participated in an experiment examining the efficacy of a simulation to assist technicians in rapidly understanding a system's state. Participants were assigned to one of three groups based on the technicians' experience and one of two experimental conditions: simulation (SIM) or technical manual (TM). The experimental task consisted of a series of eight questions regarding the condition of the S-3 aircraft's nose wheel steering (NWS) system given a set of initial aircraft conditions. To aid in performance of the experimental task, participants assigned to the TM condition were given a paper copy of the S-3 aircraft's organizational maintenance manual for the NWS system, and participants assigned to the SIM condition were given a laptop computer running a computer-based interactive model of the S-3 NWS system. Results showed that regardless of level of expertise, participants assigned to the SIM condition answered questions significantly faster than participants assigned to the TM condition. Further, technicians experienced in nonaviation maintenance assigned to the SIM condition answered questions significantly more accurately than experienced nonaviation technicians assigned to the TM condition.
