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.     

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.     

Probability as a psychological distance: Construal and preferences

We argue that probability, like space and time, instantiates psychological distance. Unlikely outcomes may seem more remote than likely outcomes and may therefore be construed at a relatively high level. Specifically, when the probability of an outcome is low, ends-related primary features should be more salient than means-related secondary features, but as the probability of the outcome increases, means-related features may become no less and even more salient than ends-related features. Thus, increases in probability should increase the weight of means-related features relative to the weight of ends-related features in decisions, thereby decreasing (or even reversing) the preference for a more desirable/less feasible outcome over a less desirable/more feasible outcome. We observed this pattern in two experiments. Analyses of judgments, monetary decisions, and self-reported reasons for decisions showed that the weight of means-related features was more sensitive to changes in probability than the weight of ends-related features in decisions.

“It’s Really No Big Deal”: The Role of Social Supply Networks in Normalizing Use of Cannabis by Students at Canadian Universities

Cannabis (marijuana) has undergone a normalizing process as indicated by high use rates, social tolerance, and broader cultural acceptance of its use in many countries. Users also maintain access through extended friendship networks that facilitate the cultural diffusion of the practice. The social nature of supply is herein theorized in terms of Goffman’s understanding of activities that function to preserve a sense of normalcy as a collective achievement enabling predictable constructions of reality. Based on in-depth interviews with undergraduate students, we explore how social networks of supply—characterized by casual access, reciprocity, and sharing—contribute to shared meanings about using marijuana as an unremarkable or “normal” thing to do.     

Effectiveness of Acceptance–Commitment Therapy on Craving Beliefs in Patients on Methadone Maintenance Therapy: A Pilot Study

The present study is designed to evaluate the efficacy of acceptance–commitment therapy (ACT) on craving beliefs in opioid dependent patients on methadone maintenance treatment (MMT). Twenty-eight opioid dependent participants, aged 18–50 years, who were on MMT based on Iran’s Ministry of Health and Medical Education published protocol, were evaluated in Mashhad during 2011–2012. The treatment group comprised fourteen participants, who received eight sessions of individual ACT alongside MMT while fourteen participants of the control group received just MMT. The effectiveness of the intervention was assessed by the craving beliefs questionnaire (CBQ), the action and acceptance questionnaire (AAQ-I) and the mean dosage of methadone the participants consumed in the last 3 days. Assessment was performed three times; the first was before the initiation of ACT (as pretest), the second was 2 weeks after ACT was terminated (as posttest), and the third one was 12 weeks after the termination of ACT (as follow-up). The extracted data were analyzed by two way ANOVA and ANCOVA using SPSS-20. While there was no significant difference in the mean methadone dosage between the treatment and the control group at pretest (p = 0.067), patients in the treatment group had a significantly lower methadone dosage at posttest (p < 0.001) and follow-up (p < 0.001) compared to the control group. There was a significant reduction in the CBQ scores between treatment and control groups at posttest (p = 0.047) and follow-up (p = 0.014). There was also a significant difference in AAQ-I score between treatment and control at posttest (p < 0.001) and follow-up (p < 0.001). It seems that short-term individual ACT is associated with a significant decline in craving beliefs in substance-dependent patients, which lasts for at least 12 weeks after the termination of ACT.
