Liking and attributions of motives as mediators of the relationships between individuals' reputations,helpful behaviors,and raters' reward decisions

Two studies investigated the mediating effects of liking and attributions of motives on the relationship between a ratee's reputation and helpful behaviors and raters' reward decisions. During managerial simulations, raters evaluated individuals after watching videotapes in which the individual's reputation and helpful behaviors were manipulated. Results indicated an interaction effect between reputation and helpful behaviors such that a helpful person with a good reputation received more rewards than did a helpful person with a bad reputation. In contrast, an unhelpful person with a good reputation did not receive better rewards than an unhelpful person with a bad reputation. Moreover, raters' liking of ratees and the motives raters attributed to ratees' helpful behaviors mediated the relationship between the manipulations and raters' reward decisions.     

Is depression taxonic,dimensional, or both?

The current investigation examines the potential importance of item selection in the ongoing discussion regarding the taxonicity of depression. Following J. C. Coyne (1994), we contrast the taxonicity of "distress" with the taxonicity of a syndrome more focused on somatic symptoms (i.e., the involuntary defeat syndrome). Using 4 samples of 984 undergraduates, we first replicate the J. Ruscio and A. M. Ruscio (2000) results by showing that distress item indicators are dimensional. We then demonstrate taxonicity using items focused on somatic symptoms and reflective of disruption of multiple homeostatic mechanisms. Results suggest that item selection is central to the determination of taxonicity in depression.     

Conflicting processes in the extinction of conditioned taste aversion: behavioral and molecular aspects of latency,apparent stagnation,and spontaneous recovery

The study of experimental extinction and of the spontaneous recovery of the extinguished memory could cast light on neurobiological mechanisms by which internal representations compete to control behavior. In this work, we use a combination of behavioral and molecular methods to dissect subprocesses of experimental extinction of conditioned taste aversion (CTA). Extinction of CTA becomes apparent only 90 min after the extinction trial. This latency is insensitive to muscarinic and β-adrenergic modulation and to protein synthesis inhibition in the insular cortex (IC). Immediately afterwards, however, the extinguishing trace becomes sensitive to β-adrenergic blockade and protein synthesis inhibition. The subsequent kinetics and magnitude of extinction depend on whether a spaced or massed extinction protocol is used. A massed protocol is highly effective in the short run, but results in apparent stagnation of extinction in the long-run, which conceals fast spontaneous recovery of the preextinguished trace. This recovery can be truncated by a β-adrenergic agonist or a cAMP analog in the insular cortex, suggesting that spontaneous overtaking of the behavioral control by the original association is regulated at least in part by β-adrenergic input, probably operating via the cAMP cascade, long after the offset of the conditioned stimulus. Hence, the performance of the subject in experimental extinction is the sum total of multiple, sometimes conflicting, time-dependent processes.     

Effect of endogenous attention on detection of weak gustatory and olfactory flavors

The effect of endogenous attention on the detectability of weak flavorants was examined in an absolute detection (two-alternative forced-choice) task. Attention to sucrose improved the detectability of sucrose, a gustation-based flavorant, both when the alternative was water and when it was vanillin. But attention to vanillin did not improve the detectability of vanillin, an olfaction-based flavorant, either when the alternative was water or when it was sucrose. Nor did attention improve the detectability of vanillin when the alternative was citric acid, a tastant that is qualitatively less similar to vanillin than is sucrose. Attention had no positive effect on the detection of either sucrose or vanillin when it was mixed with the other substance. These findings suggest that although it is possible to attend selectively to gustatory flavors, it may be more difficult to attend selectively to olfactory flavors--perhaps because attention to flavors, which are taken in the mouth, is directed spatially toward the tongue, where gustatory, but not olfactory, receptors are located.     

The problem of arbitrary requirements: an abrahamic perspective

Games,Rules, and Practices

We present and defend a view labeled “practiceism” which provides a solution to the incompatibility problems. The classic incompatibility problem is inconsistency of: 1. Someone who intentionally violates the rules of a game is not playing the game.

2. In many cases, players intentionally violate the rules as part of playing the game (e.g. fouling to stop the clock in basketball).

The problem has a normative counterpart: 1’. In normal cases, it is wrong for a player to intentionally violate the rules of the game.

2’. In many normal cases, it is not wrong for a player to intentionally violate the rules of the game (e.g. fouling to stop the clock in basketball).

According to both formalism and informalism, the rules of the game include the formal rules of the game. Both traditional positions avoid the incompatibility problems by rejecting 1 and 1'. Practiceism rejects 2 and 2’: it maintains that the rules are the rules manifested in playing the game, not the formal rules.

Practiceism presents two theses: (a) the real rules of the game are the rules players follow: the practice determines the rules, and not vice versa. (b) the (first order) rules of a game determine what is legitimate within the game.     

Combined visual illusion effects on the perceived index of difficulty and movement outcomes in discrete and continuous fitts’ tapping

The speed-accuracy trade-off is a fundamental movement problem that has been extensively investigated. It has been established that the speed at which one can move to tap targets depends on how large the targets are and how far they are apart. These spatial properties of the targets can be quantified by the index of difficulty (ID). Two visual illusions are known to affect the perception of target size and movement amplitude: the Ebbinghaus illusion and Muller-Lyer illusion. We created visual images that combined these two visual illusions to manipulate the perceived ID, and then examined people’s visual perception of the targets in illusory context as well as their performance in tapping those targets in both discrete and continuous manners. The findings revealed that the combined visual illusions affected the perceived ID similarly in both discrete and continuous judgment conditions. However, the movement outcomes were affected by the combined visual illusions according to the tapping mode. In discrete tapping, the combined visual illusions affected both movement accuracy and movement amplitude such that the effective ID resembled the perceived ID. In continuous tapping, none of the movement outcomes were affected by the combined visual illusions. Participants tapped the targets with higher speed and accuracy in all visual conditions. Based on these findings, we concluded that distinct visual-motor control mechanisms were responsible for execution of discrete and continuous Fitts’ tapping. Although discrete tapping relies on allocentric information (object-centered) to plan for action, continuous tapping relies on egocentric information (self-centered) to control for action. The planning-control model for rapid aiming movements is supported.     

Are Religious Coping and Pain Perception Related Together? Assessment in Iranian Cancer Patients

Pain of cancer had various significant side effects that based on the literature it can reduced by religious coping methods. This study aimed to investigate the relationship between religious coping and pain perception in Iranian cancer patients. In this cross-sectional study (October–December, 2015), 380 hospitalized cancer patients were entered to the study using accessible sampling. Data were collected by socio-demographic, Religious Coping and McGill pain questionnaires. Males (48.39 ± 13 ± 39; CI95: 46.41–50.38) are older than females (45.33 ± 18.44; CI95: 42.79–47.87). According to results, there was a significant relationship between pain perception and positive religious coping in cancer patients. Also there was a significant relationship between pain perception and family history of cancer (P < 0.05). It seems that improving the level and quality of positive religious affiliation can be effective on the amount of stimulation and pain of cancer patients. Of course, more comprehensive studies are needed to be achieved more reliable results about the effects of religious coping on pain perception in these patients.
