Recognition models of alphanumeric characters

Several methods to study the recognition and similarity of alphanumeric characters are briefly discussed and evaluated. In particular, the application of the choice-model (Luce, 1959, 1963) to recognition of letters is criticized. A feature analytic model for recognition of alphanumeric characters based on Tversky’s (1977) features of similarity is proposed and tested. It is argued that the proposed model: (a) is parsimonious in that it utilizes a relatively small number of parameters, (b) is psychologically more meaningful compared with other approaches in that it is attempting to study underlying processes rather than just reveal a similarity structure, (c) yields predictions that have a high level of fit with the observed data. Possible implications from the use of the model for future research are briefly discussed.     

The authority of pleasure

The aim of the paper is to reassess the prospects of a widely neglected affective conception of the aesthetic evaluation and appreciation of art. On the proposed picture, the aesthetic evaluation and appreciation of art are non‐contingently constituted by a particular kind of pleasure. Artworks that are valuable qua artworks merit, deserve, and call for a certain pleasure, the same pleasure that reveals (or at least purports to reveal) them to be valuable in the way that they are, and constitutes their aesthetic evaluation and appreciation. This is why and how art is non‐contingently related to pleasure. Call this, the Affective View. While I don't advance conclusive arguments for the affective view in this paper, I aim to reassess its prospects by (1) undermining central objections against it, (2) dissociating it from hedonism about the value of artworks (the view that this value is grounded in, and explained by, its possessors’ power to please), and (3) introducing some observations on the practice of art in support of it. Given that the objections I discuss miss their target, and given the observations in support of it, I conclude that the affective view is worth serious reconsideration.     

On Liking Aesthetic Value

According to tradition, aesthetic value is non-contingently connected to a certain feeling of liking or pleasure. Is that true? Two answers are on offer in the field of aesthetics today: 1. The Hedonist answers: Yes, aesthetic value is non-contingently connected to pleasure insofar as this value is constituted and explained by the power of its possessors to please (under standard conditions). 2. The Non-Affectivist answers: No. At best, pleasure is contingently related to aesthetic value. The aim of this paper is to point to a blind spot in the dialectic between these two standard positions by defending a third neglected answer to the question above, the answer of the Value-Meriting-Pleasure [VMP] advocate. According to this answer, a certain kind of (cognitive and responsive) pleasure is connected to aesthetic value non-contingently, but also non-hedonically. VMP is the view that objects of aesthetic value are non-contingently related to pleasure insofar as they merit a certain kind of pleasure. But, pace the hedonist, those objects are valuable (those that are to be engaged with etc.) neither on account of their capacity to give pleasure nor on account of the hedonic value of the attitude they merit.     

The role of negative features in joint and separate evaluation

Separate and joint evaluations differ in the manner in which attribute information is processed. We propose that negative attributes weigh more in separate compared to joint ratings. To assess the relative weights of positive and negative attributes, stimuli were employed containing mixed attribute valence, with good and poor attributes. In three experiments it was demonstrated empirically that, using such mixed valence options, the negative attributes indeed weighed more than the positive ones in separate compared to joint ratings. Direct evidence for the increased weight of negative attributes in separate ratings was provided by showing preference shifts between joint and separate ratings for options with mixed attribute valence.

Effects of stress on sleep: the moderating role of coping style.

The aim of this prospective quasi-experimental study was to assess the role of coping style as a factor moderating the relationship between stress and sleep. Sleep of 36 students was assessed by means of actigraphy and daily logs during low-stress and high-stress periods. The high-stress period was the week that the students were evaluated for acceptance to graduate programs in clinical psychology. The low-stress period was a regular academic week. The students' ways of coping were assessed during the baseline low-stress period using the COPE inventory. Data analysis revealed that a high emotion-focused coping score was significantly predictive of reduction in sleep time from the low- to the high-stress period. These results suggest that coping style is a key factor in assessing the relationship between stress and sleep.     

Life With a Partner with ADHD: The Moderating Role of Intimacy

Adult attention deficit and hyperactivity disorder (ADHD) manifests itself through a variety of symptoms, some of which affect not only occupational and recreational activities but also intimate relationships. Previous findings have focused on the effects of adult ADHD on intimacy and relationships from the ADHD diagnosed person’s point of view. However, spouses of people with ADHD are a neglected population with regard to the effects that ADHD has on their romantic relationships. Our aim was to assess the effects of being married to a spouse with ADHD on marital relationships, and the moderating role of intimacy. We compared healthy spouses of people with ADHD to healthy spouses of healthy adults (M?=?38.23, SD?=?4.78) in their degree of self-reported intimacy and marital satisfaction. Our findings indicate that spouses of individuals with ADHD report significantly lower intimacy and lower marital satisfaction compared to spouses of individuals without ADHD. Moreover, our findings indicate that spousal reports about their degree of intimacy mediate the relationships between their spouses’ ADHD and their marital satisfaction. Results are discussed in relation to the broad implications that adult ADHD has for romantic intimacy. Our research addresses healthy partners married to a spouse with ADHD, suggesting that living with a partner with ADHD behaviors is challenging. ADHD symptoms negatively affect various qualities in the person experiencing them, but of equal importance is the damage occurring to his or her spouse. Implications for future research and recommendations for clinical work are suggested.     

Make it to work (and back home) safely: the effect of psychological work stressors on employee behaviour while commuting by car

Despite empirical data suggesting that commuting accidents are a major problem worldwide, research on employee behaviour while commuting by car is scant. In particular, our understanding of the antecedents of unsafe commuting behaviour is limited mainly to demographic variables and work-related physical stressors. Our study addressed this lacuna by investigating the association between work-related psychological stressors and unsafe commuting behaviour. In addition, we developed and validated a scale for measuring commuting norms and considered the permissiveness of these norms as a mediator in the stressor-commuting behaviour association. The results, based on data collected from 216 employees in a large manufacturing plant at 2 points in time, indicated that abusive supervision and work–family conflict were both positively related to unsafe commuting behaviour, and that the permissiveness of commuting norms partially mediated these relationships. The potential role of work organizations in educating employees about commuting behaviour and driving safety is discussed.     

Adult romantic relationships as contexts of human development: a multimethod comparison of same-sex couples with opposite-sex dating, engaged, and married dyads

This article presents a multimethod, multi-informant comparison of community samples of committed gay male (n=30) and lesbian (n=30) couples with both committed (n=50 young engaged and n=40 older married) and noncommitted (n=109 exclusively dating) heterosexual pairs. Specifically, in this study the quality of same- and opposite-sex relationships was examined at multiple levels of analysis via self-reports and partner reports, laboratory observations, and measures of physiological reactivity during dyadic interactions. Additionally, individuals in same-sex, engaged, and marital relationships were compared with one another on adult attachment security as assessed through the coherence of participants' narratives about their childhood experiences. Results indicated that individuals in committed same-sex relationships were generally not distinguishable from their committed heterosexual counterparts, with one exception--lesbians were especially effective at working together harmoniously in laboratory observations.     

Speaker–listener incompatibility: Joint and separate processing in risky choice framing

Framing effects are considered in a conversational framework using the well-known Asian Disease problem [Tversky, A., & Kahneman, D. (1981). The framing of decisions and the psychology of choice. Science, 211, 453–458]. Speakers’ preferred message framing is examined and its corresponding persuasiveness is assessed using listeners’ responses. The results show that speakers exhibit a marked and consistent preference for positive over negative framing (Experiment 1). Judged from listeners’ responses, this preference is effective for promoting riskless, but not risky options. The incompatibility between speakers and listeners may be resolved by noting that speakers can jointly (i.e., comparatively) assess the information and the persuasive qualities of alternative frames. In contrast, listeners are exposed only to one of these frames and, consequently, can only assess the information separately (i.e., non-comparatively). Experiments 2 and 3 demonstrate that no incompatibility exists when both speakers and listeners are either in separate, or in joint evaluation mode. Differences between risky choice and attribute framing [Levin, I.P., Schneider, S.L., & Gaeth, G.J. (1998). All frames are not created equal: a typology and critical analysis of framing effects. Organizational Behavior and Human Decision Processes, 76, 149–188] are briefly discussed.
