Valid distinctions between conscious and unconscious perception?

In this commentary, we discuss the strengths and limitations of Snodgrass, Bernat, and Shevrin's (2004) theory of unconscious perception. Our commentary centers on the value of signal detection theory (SDT) to understanding the unconscious perception controversy, a value that Snodgrass et al. for the most part agree with (i.e., that most approaches to studying unconscious perception are invalid because they have confounded the criterion for detection with the criterion for awareness). However, we believe that their model relies on a somewhat restricted application of SDT. We discuss how SDTcan be better applied to provide the necessary tests to validate their model.     

Assessing the causal structure of function

Theories typically emphasize affordances or intentions as the primary determinant of an object's perceived function. The HIPE theory assumes that people integrate both into causal models that produce functional attributions. In these models, an object's physical structure and an agent's action specify an affordance jointly, constituting the immediate causes of a perceived function. The object's design history and an agent's goal in using it constitute distant causes. When specified fully, the immediate causes are sufficient for determining the perceived function--distant causes have no effect (the causal proximity principle). When the immediate causes are ambiguous or unknown, distant causes produce inferences about the immediate causes, thereby affecting functional attributions indirectly (the causal updating principle). Seven experiments supported HIPE's predictions.     

Type-based bigram frequencies for five-letter words

Researchers often require subjects to make judgments that call upon their knowledge of the orthographic structure of English words. Such knowledge is relevant in experiments on, for example, reading, lexical decision, and anagram solution. One common measure of orthographic structure is the sum of the frequencies of consecutive bigrams in the word. Traditionally, researchers have relied ontoken-based norms of bigram frequencies. These norms confound bigram frequency with word frequency because each instance (i.e., token) of a particular word in a corpus of running text increments the frequencies of the bigrams that it contains. In this article, the authors report a set oftype-based bigram frequencies in which each word (i.e., type) contributes only once, thereby unconfounding bigram frequency from word frequency. The authors show that type-based bigram frequency is a better predictor of the difficulty of anagram solution than is token-based frequency. These norms can be downloaded fromwww.psychonomic.org/archive/.     

Emotion Regulation and the Specific Associations with Health Anxiety

This study investigated two primary research aims surrounding health anxiety: (a) to examine what differences exist in emotion regulation strategies of health anxious and non-health anxious populations and (b) to investigate what emotion regulation strategies predict health anxiety, before and after controlling for trait cognitive and somatic anxiety. A total of 95 participants of the general population completed a series of online questionnaires. A single factor between groups MANOVA revealed that a health anxious group scored significantly higher in several emotion regulation strategies: distraction, external attribution, emotion expression and acting out; anxiety-related variables: trait cognitive and somatic anxiety; and beliefs about the negative consequences of becoming ill. Hierarchical regressions showed that several emotion regulation strategies were significantly associated with higher levels of health anxiety, before: distraction, external attribution, capitalising, positive reappraisal and emotional expression; and after: external attribution and capitalising, the control of trait anxiety. Overall, the results demonstrated that (a) emotional intelligence and behavioural attempts to understand emotional experiences may be associated with specific health anxiety symptomology, while a lack of effective cognitive strategies and worry may be responsible for the associated trait anxiety dimensions.     

Spatiotemporal competition and task-relevance shape the spatial distribution of emotional interference during rapid visual processing: Evidence from gaze-contingent eye-tracking

People’s ability to perceive rapidly presented targets can be disrupted both by voluntary encoding of a preceding target and by spontaneous attention to salient distractors. Distinctions between these sources of interference can be found when people search for a target in multiple rapid streams instead of a single stream: voluntary encoding of a preceding target often elicits subsequent perceptual lapses across the visual field, whereas spontaneous attention to emotionally salient distractors appears to elicit a spatially localized lapse, giving rise to a theoretical account suggesting that emotional distractors and subsequent targets compete spatiotemporally during rapid serial visual processing. We used gaze-contingent eye-tracking to probe the roles of spatiotemporal competition and memory encoding on the spatial distribution of interference caused by emotional distractors, while also ruling out the role of eye-gaze in driving differences in spatial distribution. Spontaneous target perception impairments caused by emotional distractors were localized to the distractor location regardless of where participants fixated. But when emotional distractors were task-relevant, perceptual lapses occurred across both streams while remaining strongest at the distractor location. These results suggest that spatiotemporal competition and memory encoding reflect a dual-route impact of emotional stimuli on target perception during rapid visual processing.     

Putting the accreditation cart before the aaasp horse: A reply to silva,conroy and zizzi

Abstract

While Silva et al. (1999) must be congratulated for leading a discussion of accreditation of graduate programs in applied sport psychology, the authors appear to have “put the cart before the horse.” They have adopted an extreme one-sided position that suggests that accreditation of programs is the only viable solution for some of the training and employment problems that currently exist in the applied sport psychology profession. This response questions some of their assumptions and conclusions and offers several alternative solutions to these problems in a more balanced analysis of the current situation. It is hoped that these articles will stimulate further discussion at AAASP meetings and among practicing professionals.     

The MMPI–2 Restructured Clinical (RC) Scales and Redundancy: Response to Tellegen,Ben-Porath,and Sellbom

In this article, we examine 5 criticisms of Tellegen, Ben-Porath, and Sellbom (2009/this issue) about our study demonstrating the redundant relationships of the Restructured Clinical (RC) scales with extant MMPI–2 scales. We discuss differences in univariate versus multivariate comparisons of the RC scales and our “proxy” scales using their data. We show that (a) both the RC and extant proxy scales identified in our analyses account for most of the variance in the Clinical scales; (b) the proxy scales are redundant with the RC scales; (c) the proxy scales matched the 6 RC scales in accounting for variance in the Clinical scales exactly in three cases, differed by ≤.02 in 2 cases, and reached a maximum of .11 in one case; (d) the item overlap between RC1 and HEA is not at issue but rather their correlation with Scale 1; and (e) the evidence for the construct validity of the RC scales is weak using findings on the incremental validity of RC4 as illustrative.     

Are fear-avoidance beliefs related to the inception of an episode of back pain? A prospective study

Abstract

Fear-avoidance beliefs and catastrophizing have been implicated in chronic pain and theoretical models have been developed that feature these factor in the transition from acute to chronic pain. However, little has been done to determine whether these factors occur in the general population or whether they arc associated with the inception of an episode of neck or back pain. The aim of this study was to evaluate prospectively the effects of fear-avoidance beliefs and catastrophizing on the development of an episode of self-reported pain and associated physical functioning. To achieve this, we selected a sample of 415 people from the general population who reported no spinal pain during the past year. At the pretest a battery of questionnaires was administered to assess beliefs about pain and activity and it featured the Pain Catastrophizing Scale and a modified version of the Fear-Avoidance Beliefs Questionnaire. One year later outcome was evaluated by self-reports of the occurrence of a pain episode as well as a self-administered physical function test. The results showed that scores on both fear-avoidme and cabstrophizing were quite low. During the one year follow-up, 19% of the sample suffered an episode of back pain. Those with scores above the median on fear-avoidance beliefs at the pretest had twice the risk of suffering an episode of back pain and a 1.7 times higher risk of lowered physical function at the follow-up. Catastrophizing was somewhat less salient, increasing the risk of pain or lowered function by 1.5. but with confidence intervals falling below unity. These data indicate that fear-avoidance beliefs may be involved at a very early pint in the development of pain and associated activity problems in people with back pain. Theoretically. our results support the idea that fear-avoidance beliefs may develop in an interaction with the experience of pain. Clinically, the results suggest that catastrophizing and particularly fear-avoidance beliefs are important in the development of a pain problem and might be of use in screening procedures.     

The relation of self-supporting personality, enacted social support, and perceived social support

This study examines the relational model of self-supporting personality, enacted social support, and perceived social support in a sample of 482 Chinese high school students using the Self-Supporting Personality Scale for Adolescent Students (SSPS-AS), the Social Support Rating Scale (SSRS), and the Multidimensional Scale of Perceived Social Support (MSPSS). Results from the cross-sectional structural equation analyses revealed that interpersonal initiative, interpersonal openness, personal openness and personal initiative predicted perceived social support through the mediating role of enacted social support, while interpersonal responsibility, interpersonal flexibility, and personal initiative predicted perceived social support directly. Thus, the hypothesized relational model of personality, enacted social support, and perceived social support was supported. The positive relational schema may be the main underpinning of the relation of self-supporting personality, enacted social support, and perceived social support. Culture also may influence the relation.     

Maintaining One's Self-Image Vis-à-Vis Others: The Role of Self-Affirmation in the Social Evaluation of the Self

Three studies examined how people maintain their self-images when they face threat to interpersonal aspects of the self. In Studies 1 and 2, we found evidence that low self-esteem people lower their estimates of their performance when they expect immediate feedback in order to protect themselves from the interpersonal threat inherent in such feedback, and that self-affirmation reduces this tendency among low self-esteem people. In Study 3, we found that when people are self-affirmed they are more likely to engage in upward social comparisons and less likely to engage in downward social comparisons. Together these findings suggest that people can cope with threats to interpersonal aspects of the self by affirming other important aspects of the self.
