Invariants and Information Pickup in The Senses Considered as Perceptual Systems: Implications for the Experimental Analysis of Behavior

ABSTRACT

Although Gibson focused his agenda on the study of perception and Skinner on learning as contingencies of reinforcement, they shared a nonrepresentational approach. We propose that the ecological concept of invariants developed in Gibson's book The Senses Considered as Perceptual Systems (1966) could underlie Skinner's notion of contingencies of reinforcement as environmental opportunities for behaving. The proposal is divided in 3 parts: the concept of stimulus for perception, the role of the notion of invariants in the operant contingency, and the information for perception and behavior. We conclude that approximating contingencies of reinforcement as instances of environmental invariants can be fruitful for studying a number of phenomena within the context of operant conditioning.     

Applying Person‐Centered Counseling to Sexual Minority Adolescents

Drawing attention to the very unique and complex needs of stigmatized sexual minority youth, the authors explore the therapeutic potential of person‐centered counseling in helping lesbian, gay, bisexual, transgender/sexual (LGBT) adolescents who are working toward the acceptance and disclosure of their sexual identity. They suggest that person‐centered counseling embodies 6 aspects that are particularly helpful to LGBT adolescent clients and propose 3 additional methods that compensate for the limitations of the person‐centered approach in this particular helping context.     

Traumatic stress, perceived global stress, and life events: prospectively predicting quality of life in breast cancer patients.

The authors investigated the relationship between stress at initial cancer diagnosis and treatment and subsequent quality of life (QoL). Women (n = 112) randomized to the assessment-only arm of a clinical trial were initially assessed after breast cancer diagnosis and surgery and then reassessed at 4 months (during adjuvant treatment) and 12 months (postadjuvant treatment). There were 3 types of stress measured: number of stressful life events (K. A. Matthews et al., 1997), cancer-related traumatic stress symptoms (M. J. Horowitz, N. Wilner, & W. Alvarez, 1979), and perceived global stress (S. Cohen, T. Kamarck, & R. Mermelstein, 1983). Using hierarchical multiple regressions, the authors found that stress predicted both psychological and physical QoL (J. E. Ware, K. K. Snow, & M. Kosinski, 2000) at the follow-ups (all ps < .03). These findings substantiate the relationship between initial stress and later QoL and underscore the need for timely psychological intervention.     

Social Dominance Theory: Its Agenda and Method

The theory has been misconstrued in four primary ways, which are often expressed as the claims of psychological reductionism, conceptual redundancy, biological reductionism, and hierarchy justification. This paper addresses these claims and suggests how social dominance theory builds on and moves beyond social identity theory and system justification theory.     

Motor skill learning in the middle-aged: limited development of motor chunks and explicit sequence knowledge

The present study examined whether middle-aged participants, like young adults, learn movement patterns by preparing and executing integrated sequence representations (i.e., motor chunks) that eliminate the need for external guidance of individual movements. Twenty-four middle-aged participants (aged 55–62) practiced two fixed key press sequences, one including three and one including six key presses in the discrete sequence production task. Their performance was compared with that of 24 young adults (aged 18–28). In the middle-aged participants motor chunks as well as explicit sequence knowledge appeared to be less developed than in the young adults. This held especially with respect to the unstructured 6-key sequences in which most middle-aged did not develop independence of the key-specific stimuli and learning seems to have been based on associative learning. These results are in line with the notion that sequence learning involves several mechanisms and that aging affects the relative contribution of these mechanisms.     

Personal Values and Well-Being among Europeans,Spanish Natives and Immigrants to Spain: Does the Culture Matter?

The aim of this study was to analyze the relationship between personal values and well-being. Two correlational studies are presented with the following random samples: (1) four native samples: two samples from the 2006 European Social Survey (Europe n1 = 28,375, Spain n2 = 1,321) and two Basque samples (n3 = 1,770; n4 = 820); and (2) a sample of immigrants in the Basque Country (quasirandom) (n5 = 1,171). Age range of respondents was 18–60 years. The instruments used were for measuring: (1) personal values (Schwartz’s PVQ-40 or PVQ-21), and (2) well-being (Bradburn’s PNA, Goldberg’s GHQ, and life satisfaction and perceived control items from the World Value Survey). Partial correlation analysis was applied, with PVQ scale response bias controlled. The data supported a positive association of hedonic and psychological well-being with openness to experience and individualist values, and a negative association with power and conservation or collectivist values. Satisfaction with life partially mediated the relationship between personal values and affect. The results support a universal association of healthy values with well-being.     

Can you see me in the snow? Action simulation aids the detection of visually degraded human motion

Using a novel paradigm, we demonstrate that action simulation can directly facilitate ongoing perception of people's movements. Point-light actors (PLAs) representing common human motions were shown embedded in a visual noise reminiscent of "TV snow". At first, the PLAs were perceived clearly, then occluded from view for a short duration, during which it was hypothesized that a real-time action simulation was generated tracking the motion's course. The PLA then reappeared in motion at variable visibility against the noise, whilst detection thresholds for the reappearance were measured. In the crucial manipulation, the test motion was either temporally congruent with the motion as it would have continued during occlusion, and thus temporally matching the simulation, or temporally incongruent. Detection thresholds were lower for congruent than for incongruent reappearing motions, suggesting that reappearing motion that temporally matched the internal action simulation was more likely to be detected.     

Extending end-state comfort effect: do we consider the beginning state comfort of another?

Sharing a drink or passing a tool to another person is frequently done in our daily lives. However, a second thought is rarely given about how the object should be handed; instead we pay attention to other factors (e.g., the company). This interaction (handing a tool to someone) is interesting, since it may give insight to how motor intentions are predicted. Research has demonstrated that individuals exhibit an end-state comfort effect when manipulating objects, and it is of interest to determine how this is applied to a joint-action paradigm. The purpose of this experiment was to determine if participants would anticipate the confederate's postural requirements and pass tools in a manner that allowed the confederate to have beginning state comfort and thus facilitate the motion sequence as a whole. That is, would the participant incur the cost of the movement by adopting an awkward posture to facilitate the use of the tool by the confederate? The results demonstrated that participants allowed the confederate to adopt a comfortable beginning state comfort on 100% of the trials for all the tools. However, the participants did not sacrifice end-state comfort, demonstrating that the participants were able to plan ahead to both maximize their own end-state comfort and the beginning state comfort of the confederate.     

Career decision status as a predictor of resignation behavior five years later

This paper extends earlier research exploring the relationship between career decision status and work outcomes by examining resignation behavior in a group of new graduates five years after initial appointment. On appointment various measures were collected including career decision status variables. Earlier research identified a significant relationship between a number of important work outcomes and career decision status. In the current study two variables–career decidedness and career choice importance–predicted resignation behavior. Those people who on appointment scored higher on career decidedness or lower on career choice importance were significantly more likely to stay in the organization than others. The implications of this finding for individuals and organizations are discussed.     

Ethnic Minority‐Majority Asymmetry in National Attitudes around the World: A Multilevel Analysis

Using data from the International Social Survey Programme, this research investigated asymmetric attitudes of ethnic minorities and majorities towards their country and explored the impact of human development, ethnic diversity, and social inequality as country‐level moderators of national attitudes. In line with the general hypothesis of ethnic asymmetry, we found that ethnic, linguistic, and religious majorities were more identified with the nation and more strongly endorsed nationalist ideology than minorities (H1, 33 countries). Multilevel analyses revealed that this pattern of asymmetry was moderated by country‐level characteristics: the difference between minorities and majorities was greatest in ethnically diverse countries and in egalitarian, low inequality contexts. We also observed a larger positive correlation between ethnic subgroup identification and both national identification and nationalism for majorities than for minorities (H2, 20 countries). A stronger overall relationship between ethnic and national identification was observed in countries with a low level of human development. The greatest minority‐majority differences in the relationship between ethnic identification and national attitudes were found in egalitarian countries with a strong welfare state tradition.
