Action matters: The role of action plans and object affordances in selection for action

In a series of three experiments requiring selection of real objects for action, we investigated whether characteristics of the planned action and/or the “affordances” of target and distractor objects affected interference caused by distractors. In all ofthe experiments, the target object was selectedon the basis of colour and was presented alone or with a distractor object. We examined the effect of type of response (button press, grasping, or pointing), object affordances (compatibility with the acting hand, affordances for grasping or pointing), and target/distractor positions (left or right) on distractor interference (reaction time differences between trials with and without distractors). Different patterns of distractor interference were associated with different motor responses. In the button-press conditions of each experiment, distractor interference was largely determined by perceptual salience (e.g., proximity to initial visual fixation). In contrast, in tasks requiring action upon the objects in the array, distractors with handles caused greater interference than those without handles, irrespective of whether the intended action was pointing or grasping. Additionally, handled distractors were relatively more salient when their affordances for grasping were strong (handle direction compatible with the acting hand) than when affordances were weak. These data suggest that attentional highlighting of specific target and distractor features is a function of intended actions.     

Understanding the impact of HIV diagnosis amongst gay men in Scotland: An interpretative phenomenological analysis

Objectives: Although a wide literature details the psychological impact of human immunodeficiency virus (HIV) diagnosis, it predates the introduction of effective treatment for HIV (i.e. anti-retroviral therapies, ARTs). This article explores the psychological impact of HIV diagnosis in post-ART accounts. This is important, given the recent policy developments which focus upon increasing HIV testing and thus diagnoses.

Design: This study presents a qualitative exploration of the experiential accounts of HIV-positive gay men living in Scotland. A total of 14 HIV-positive gay men took part in open-ended interviews.

Methods: Interpretative phenomenological analysis was employed to identify recurrent themes across the interviews.

Results: Our analysis focuses upon the participants’ struggles in adjusting to their HIV status. Diagnosis was a deeply shocking and unexpected experience. Stigma and fear of prejudice dominated their accounts. HIV was understood, variously, as a shameful, fatal and life-changing condition. Overall, within these accounts there was little sense of HIV normalisation.

Conclusions: In Scotland, where HIV prevalence is low, and where no accessible HIV-positive sub-culture exists, there is on-going psychological distress and morbidity amongst gay men testing HIV positive. As HIV-related policy increasingly focuses on increasing rates of antibody testing, there is a need to reduce the psychosocial costs associated with HIV-positive diagnoses.     

Understanding organizational resilience in elite sport: An exploration of psychosocial processes

ObjectivesAlthough organizational resilience research has identified the characteristics of elite sport organizations that successfully deal with significant change, further research is needed to understand how they function. The objective of this study was to explore the psychosocial processes underpinning organizational resilience in elite sport.Design and methodUsing interviews supplemented by timelines compiled from documentary analysis of public online sources, data was gathered during 43 interviews with 22 participants from 10 elite sport organizations across an 8-month period. Participant roles included chief executive officers (n = 5), directors (n = 7), board members (n = 2), middle managers (n = 4), support staff (n = 2), head coach (n = 1), and senior athlete (n = 1). Reflexive thematic analysis of the data was conducted from a critical realist standpoint.ResultsThe data analysis yielded two core processes of sensing (internal and external mechanisms, diversity of perspectives, evaluating and monitoring) and adapting (mirroring current resource availability, open and frequent communication, acute versus chronic change), and two supporting processes of strengthening resources (quality and quantity of human and financial resources, relationships as source of additional resources) and shielding from risk (internal risk mitigation, external influencing). These data were interpreted to indicate that these processes are not sequential, or temporally distinct, but instead cumulatively contribute towards an organization’s resilience capability.ConclusionsAs the first empirical investigation exploring the psychosocial processes underpinning organizational resilience in elite sport, the results provide a unique framework and practical implications to help those working in and with elite sport organizations successfully navigate uncertainty and change.     

Adult attachment and body satisfaction. An exploration of general and specific relationship differences

The relationship between general and specific adult relationship attachment and body satisfaction was examined in a community sample of 133 women. Participants completed measures of body image (body surveillance, body-as-object esteem, and body-as-process satisfaction) and general attachment (anxiety and avoidance) and then were primed for a romantic partner or close friend relationship, after which they completed specific measures of attachment and body satisfaction. General attachment results replicated previous research. Specific attachment results demonstrated distinct differences both from general attachment and between romantic partner attachment and close friend attachment. Attachment independently predicted body satisfaction both for general and close friend measures; however, in romantic relationships, only body surveillance independently contributed to body satisfaction.     

Individual differences in the phenomenological impact of social stigma

In an attempt to define stigmatization from the perspective of stigmatized group members, the author focused on the development and validation of a stigmatization scale. The scale's content validity was established with the assistance of experts in the field. European American, African American, and Native American students from 5 different U.S. universities completed the Stigmatization Scale. The construct validity of the scale was suggested by its convergence with similar measures of social alienation and its divergence from measures of personal subjective well-being. The finding that both the African American and Native American students reported significantly higher stigmatization scores than did the European Americans indicated the scale's known-groups validity. African American students at a predominantly Black university reported lower stigmatization than did African American students at a predominantly White university, suggesting the scale's malleability to context.     

Conceptualizing bullying in adult professional football: A phenomenological exploration

ObjectivesThe aim of this study was to gain an in-depth insight into male professional footballers' perception of the concept of bullying and to explore the essences of this behavior within this context.Design and MethodSemi-structured interviews were conducted with 18 adult male professional football players in the UK. Data were analyzed in accordance with the principles of Interpretative Phenomenological Analysis.ResultsParticipants highlighted that key themes within Olewus' (1993) seminal definition of bullying are relevant to professional football such as repetition, power, abuse and harm doing. Notably, there were variations in footballers' views of the constituents of these themes which were explained by divergent perceptions of how the football context shaped these components of bullying. It was evident however, that certain common elements of the football environment, such as its inherent masculinity, identity conforming nature and authoritarianism helped to contextualize the players' conceptualizations of bullying.ConclusionsWhile some of the identified themes mirrored classic definitions of bullying, this concept was articulated in an individually nuanced, context dependent fashion. These findings advance bullying literature by demonstrating how professional football shapes perceptions of this concept, while highlighting the importance of contextually tailored intervention program to address bullying.     

Individual differences in relatedness and individuality: An exploration of two constructs

Sociotropy and autonomy are two personality dimensions that relate to an individual's vulnerability to depression. Independent and interdependent self-construals are two distinctive cognitive formulations of the self derived from cross-cultural research. Both of these sets of constructs reflect self and other orientations. The purpose of the present study was to empirically examine the various factors that emerge when these two constructs are integrated. 652 participants responded to the Personal Style Inventory [Robins, C. J., Ladd, J., Welkowitz, J., Blaney, P. H., Diaz, R. & Kutcher, G. (1991). The Personal Style Inventory: Preliminary validation studies of new measures of sociotropy and autonomy. Journal of Psychopathology and Behavioral Assessment, 16, 277–300.], the Sociotropy-Autonomy Scale [Clark, D. A. & Beck, A. T. (1991). Personality factors in dysphoria: A psychometric refinement of Beck's Sociotropy-Autonomy Scale. Journal of Psychopathology and Behavioral Assessment, 13, 369–388.] and the Self-Construal Scale [Singelis, T. M. (1994). The measurement of independent and interdependent self-construals. Personality and Social Psychology Bulletin, 20, 580–591.]. Four factors emerged from a factor analysis conducted on the items of the three scales measuring sociotropy-autonomy and independent and interdependent self-construal. These four factors are discussed in the context of vulnerability to depression.     

The search for freedom in extreme sports: A phenomenological exploration

Participation in extreme sports is continuing to grow, yet there is still little understanding of participant motivations in such sports. The purpose of this paper is to report on one aspect of motivation in extreme sports, the search for freedom. The study utilized a hermeneutic phenomenological methodology. Fifteen international extreme sport participants who participated in sports such as BASE jumping, big wave surfing, extreme mountaineering, extreme skiing, rope free climbing and waterfall kayaking were interviewed about their experience of participating in an extreme sport. Results reveal six elements of freedom: freedom from constraints, freedom as movement, freedom as letting go of the need for control, freedom as the release of fear, freedom as being at one, and finally freedom as choice and responsibility. The findings reveal that motivations in extreme sport do not simply mirror traditional images of risk taking and adrenaline and that motivations in extreme sports also include an exploration of the ways in which humans seek fundamental human values.     

Inter-event differences in action memory

Two experiments examined the effect of verb-noun connectivity on recall of simple action phrases, under motor and nonmotor encoding conditions. Connectivity, measured by associative overlap and rated belongingness, was found to make a difference. High-connectivity pairs are better recalled than low-connectivity pairs. Primacy effects are absent with low-connectivity pairs, but generally present with high-connectivity pairs—irrespective of encoding conditions. Inter-item action phrase differences thus influence the effects studied in action memory research. The results were discussed in terms of strategic and nonstrategic conceptions of memory for actions.     

Emotion perception and recognition: An exploration of cultural differences and similarities

The electroencephalogram (EEG) is a powerful method for investigation of different cognitive processes. Recently, EEG analysis became very popular and important, with classification of these signals standing out as one of the mostly used methodologies. Emotion recognition is one of the most challenging tasks in EEG analysis since not much is known about the representation of different emotions in EEG signals. In addition, inducing of desired emotion is by itself difficult, since various individuals react differently to external stimuli (audio, video, etc.). In this article, we explore the task of emotion recognition from EEG signals using distance-based time-series classification techniques, involving different individuals exposed to audio stimuli. Furthermore, since some of the participants in the experiment do not understand the language of the stimuli, we also investigate the impact of language understanding on emotion perception. Using time-series distances as features for the construction of new data representations, applied here for the first time to emotion recognition and related tasks, lead to excellent classification performance, indicating that differences between EEG signals can be used to build successful models for recognition of emotions, individuals, and other related tasks. In the process, we observed that cultural differences between the subjects did not have a significant impact on the recognition tasks and models.     

Ventral encoding of functional affordances: A neural pathway for identifying errors in action

Functional tool usage is a critical aspect of our daily lives. Not only must we know which tools to use for a specific action goal, we must also know how to manipulate those tools in meaningful way to achieve the goal of the action. The purpose of this study was to identify the regions of the brain critical to supporting the process of understanding errors in tool manipulation. Using fMRI, neural activations were recorded while subjects were presented with images demonstrating typical action scenes (screwdriver used on a screw), but with the tool being manipulated either correctly (screwdriver held by handle) or incorrectly (screwdriver held by bit rather than handle). Activations in fMRI for identifying correct over incorrect tool manipulation were seen along the canonical parietofrontal action network, while activations for identifying incorrect over correct tool manipulation were primarily seen at superior temporal areas and insula. We expand our hypotheses about ventral brain networks identifying contextual error to further suggest mechanisms for understanding functional tool actions, which collectively we regard as functional affordances. This proposes a fundamental role for ventral brain areas in functional action understanding.     

The how and why of disagreement among perceivers: An exploration of person models

Impression formation has been conceptualized as a process whereby perceivers form person models of others, describing what the person is like and why (Park, DeKay, & Kraus, 1994). If they exist, person models could help explain why there appears to be little consensus in personality judgments; perceivers forming different models of a person would also view them differently on trait and affect ratings. Two experiments were conducted to test assumptions of the person-model paradigm using naturalistic targets. The structure of person models was examined, along with their content. Results demonstrated that three distinct person models emerge for each target and that the majority of perceivers can easily identify with one of the three models. We found that person models were valid across different groups of perceivers, and that the models differed in terms of masculinity-femininity and affect. Implications for the person model formulation process are discussed.     

Understanding strategy differences in a fault-finding task

This article examines strategy choices for how people find faults in a simple device by using models of several strategies and new data. Diag, a model solving this task, used a single strategy that predicted the behavior of most participants in a previous study with remarkable accuracy. This article explores additional strategies used in this reasoning task that arise when less directive instructions are provided. Based on our observations, five new strategies for the task were identified and described by being modeled. These different strategies, realized in different models, predict the speed of solution while the participant is learning the task, and were validated by comparing their predictions to the observations (r² = .27 to .90). The results suggest that participants not only created different strategies for this simple fault-finding task but that some also, with practice, shifted between strategies. This research provides insights into how strategies are an important aspect of the variability in learning, illustrates the transfer of learning on a problem-by-problem level, and shows that the noisiness that most learning curves show can arise from differential transfer between problems.     

Ethnic differences in adolescent achievement. An ecological perspective.

Using data collected from a large sample of high school students, the authors challenge three widely held explanations for the superior school performance of Asian-American adolescents, and the inferior performance of African- and Hispanic-American adolescents: group differences in (a) parenting practices, (b) familial values about education, and (c) youngsters' beliefs about the occupational rewards of academic success. They found that White youngsters benefit from the combination of authoritative parenting and peer support for achievement, whereas Hispanic youngsters suffer from a combination of parental authoritarianism and low peer support. Among Asian-American students, peer support for academic excellence offsets the negative consequences of authoritarian parenting. Among African-American youngsters, the absence of peer support for achievement undermines the positive influence of authoritative parenting.     

Individual differences in phenomenological experience: states of consciousness as a function of absorption

State manifestations of the trait of absorption--a trait associated with differential responsivity to hypnosis, meditation, marijuana intoxification, and electromyograph (EMG) biofeedback--were assessed to determine (a) if absorption correlates with various (sub)dimensions of phenomenological experience, and (b) if individuals of differing absorption ability experience different states of consciousness. In two experiments 249 and 304 participants completed Tellegen's absorption scale and experienced several stimulus conditions. Each condition's phenomenological state was assessed by means of a retrospective self-report questionnaire and quantified in terms of intensity and pattern parameters. The results indicated that absorption correlated with increased and more vivid imagery, inward and absorbed attention, and positive affect; decreased self-awareness; and increased alterations in state of consciousness and various aspects of subjective experience. In addition, individuals of high absorption ability, relative to lows, experienced a different state of consciousness during ordinary, waking consciousness that became an altered state with eye closure and an hypnoticlike induction. The usefulness of the results for understanding altered-state induced procedures such as hypnosis is discussed.     

An analysis of ideomotor action.

This article presents a framework based on the work of R. H. Lotze (1852), W. James (1890), and A. G. Greenwald (1970) for understanding ideomotor actions that tend to arise when individuals watch others perform certain actions. Two principles of ideomotor action induction are distinguished: perceptual induction, in which people tend to perform the movements they see, and intentional induction, in which people tend to perform movements suited to achieve what they would like to see. In 3 experiments, ideomotor hand, head, and foot movements were studied while participants watched a ball traveling toward a target. Results showed strong support for intentional induction, weaker support for perceptual induction, and a strong impact of the effector studied. The representational basis of action induction (stimulus vs. goal representations) and the automaticity of the underlying processing (task-dependent vs. task-independent induction) were considered.
