Medical Disaster: Why Ken Mattingly Can’t Have Measles in <Emphasis Type="Italic">Apollo 13</Emphasis>

The film Apollo 13 depicts denial of illness and refusal of health care as key components of American masculinity. In the film, male astronauts and mission controllers deny vulnerability to measles and to urinary infections, as well as the need to sleep, to prove their manliness. This is symbolized by their ridicule of flight surgeon Dr. Chuck. Conversely, the astronauts’ wives are depicted admitting vulnerability, especially insomnia. Thus, the film exploits and reinforces existing strands of American culture that view admission of illness and help-seeking as appropriate for women but not men, reinforcing denial and noncompliance as desirable male behaviors.     

Performance perceptions and self-focused attention predict post-event processing after a real-life social performance situation

Background and Objectives: Cognitive approaches to social anxiety suggest that an excessive brooding about one's performance in a social situation (post-event processing; PEP) is involved in the maintenance of anxiety. To date, most studies investigating PEP were conducted in laboratory settings. The present study sought to replicate previous findings on predictors of PEP after a naturalistic social performance situation. Methods: Sixty-five students, who had to give an evaluated presentation for credits, completed measures of trait social anxiety. Immediately after their presentation, participants rated state anxiety and attentional focus during the presentation, and provided an overall evaluation of their performance. One week after the presentation, they rated PEP during the preceding week, and reappraised their performance. Results: Regression analyses demonstrated that the performance ratings after and self-focused attention during the presentation were unique predictors of PEP over and above the effects of trait and state anxiety. There was no evidence that PEP was associated with a biased recall of individual performance evaluations. Conclusions: The results support cognitive theories that emphasize the importance of negative self-perceptions in the development of social anxiety and related processes, and underline self-focused attention and self-evaluative processes as important targets during treatment.     

Delayed Match Retrieval: a novel anticipation‐based visual working memory paradigm

We tested 8‐ and 10‐month‐old infants’ visual working memory (VWM) for object‐location bindings – what is where – with a novel paradigm, Delayed Match Retrieval, that measured infants’ anticipatory gaze responses (using a Tobii T120 eye tracker). In an inversion of Delayed‐Match‐to‐Sample tasks and with inspiration from the game Memory, in test trials, three face‐down virtual ‘cards’ were presented. Two flipped over sequentially (revealing, e.g. a swirl pattern and then a star), and then flipped back face‐down. Next, the third card was flipped to reveal a match (e.g. a star) to one of the previously seen, now face‐down cards. If infants looked to the location where the (now face‐down) matching card had been shown, this was coded as a correct response. To encourage anticipatory looks, infants subsequently received a reward (a brief, engaging animation) presented at that location. Ten‐month‐old infants performed significantly above chance, showing that their VWM could hold object‐location information for the two cards. Overall, 8‐month‐olds’ performance was at chance, but they showed a robust learning trend. These results corroborate previous findings (Kaldy & Leslie, 2005; Oakes, Ross‐Sheehy & Luck, 2006) and point to rapid development of VWM for object‐location bindings. However, compared to previous paradigms that measure passive gaze responses to novelty, this paradigm presents a more challenging, ecologically relevant test of VWM, as it measures the ability to make online predictions and actively localize objects based on VWM. In addition, this paradigm can be readily scaled up to test toddlers or older children without significant modification.     

Can cognitive psychological research on reasoning enhance the discussion around moral judgments?

In this article we will demonstrate how cognitive psychological research on reasoning and decision making could enhance discussions and theories of moral judgments. In the first part, we will present recent dual-process models of moral judgments and describe selected studies which support these approaches. However, we will also present data that contradict the model predictions, suggesting that approaches to moral judgment might be more complex. In the second part, we will show how cognitive psychological research on reasoning might be helpful in understanding moral judgments. Specifically, we will highlight approaches addressing the interaction between intuition and reflection. Our data suggest that a sequential model of engaging in deliberation might have to be revised. Therefore, we will present an approach based on Signal Detection Theory and on intuitive conflict detection. We predict that individuals arrive at the moral decisions by comparing potential action outcomes (e.g., harm caused and utilitarian gain) simultaneously. The response criterion can be influenced by intuitive processes, such as heuristic moral value processing, or considerations of harm caused.     

Studies of implicit prototype extraction in patients with mild cognitive impairment and early Alzheimer's disease

Studies of incidental category learning support the hypothesis of an implicit prototype-extraction system that is distinct from explicit memory (Smith, 2008). In those studies, patients with explicit-memory impairments due to damage to the medial-temporal lobe performed normally in implicit categorization tasks (Bozoki, Grossman, & Smith, 2006; Knowlton & Squire, 1993). However, alternative interpretations are that (a) even people with impairments to a single memory system have sufficient resources to succeed on the particular categorization tasks that have been tested (Nosofsky & Zaki, 1998; Zaki & Nosofsky, 2001) and (b) working memory can be used at time of test to learn the categories (Palmeri & Flanery, 1999). In the present experiments, patients with amnestic mild cognitive impairment or early Alzheimer's disease were tested in prototype-extraction tasks to examine these possibilities. In a categorization task involving discrete-feature stimuli, the majority of subjects relied on memories for exceedingly few features, even when the task structure strongly encouraged reliance on broad-based prototypes. In a dot-pattern categorization task, even the memory-impaired patients were able to use working memory at time of test to extract the category structure (at least for the stimulus set used in past work). We argue that the results weaken the past case made in favor of a separate system of implicit prototype extraction.     

The development and classification accuracy of the life assessment questionnaire in the detection of pain-related malingering

This paper describes three phases of the development and validation of the Life Assessment Questionnaire (LAQ), a multi-scale inventory for assessing potential malingering in adults reporting chronic pain. Study 1 involved scale construction and item analysis. Discriminant validity was investigated in Study 2 by comparing scores for the clinical reference group with participants instructed to simulate chronic pain. Study 3 examined the convergent validity of the LAQ with the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and Behavioral Assessment of Pain (BAP). Results revealed that the simulation groups scored significantly higher than the clinical reference group across all scales. Receiver operating characteristic analysis revealed sensitivity and specificity scores ranging from 0.44 to 0.57 and 0.88 to 0.93, respectively. Positive predictive power values ranged between 0.79 and 0.88. Strong convergent validity was found for the LAQ. These studies demonstrated the effectiveness of the LAQ in classifying individuals who feign pain complaints, supporting the utility of the LAQ for reaching conclusions about the presence of malingering.

Linking Adult Attachment Styles to Relationship Satisfaction in Hong Kong and the United States: The Mediating Role of Personal and Structural Commitment

Maintaining a satisfying heterosexual relationship is important to many individuals?? happiness and physical health. Evolutionary theories on the formation of relationships suggest that adult attachment and relationship commitment are universal mechanisms for securing and maintaining such mating relationships. This study sought to understand how these two mechanisms may link to each other and how they in turn contribute to relationship satisfaction with one??s current partner in Hong Kong Chinese and American cultures. Similarities in the model for relationship satisfaction were found among young dating couples in the United States and Hong Kong. Specifically, attachment anxiety was positively linked to structural commitment, whereas attachment avoidance was negatively related to personal commitment. Both dimensions of attachment (anxiety and avoidance) and both components of commitment (personal and structural) were found to predict current relationship satisfaction significantly and equivalently across cultures, with the pathway from attachment avoidance to current relationship satisfaction similarly mediated by personal commitment in both cultural groups. These results were interpreted in terms of a probable universal logic informing the interpersonal dynamics involving attachment and relationship commitment.     

Primes and flankers: Source confusions and discounting

Visual identification of briefly presented target words is affected by the presence of nondiagnostic prime words that immediately precede the target, flanker words simultaneously presented adjacent to the target, and visual masks that immediately follow the target in the same location. Priming is duration dependent: In a forced choice target identification task, brief primes produce a strong preference to choose the primed alternative, whereas long primes have the opposite effect. The ROUSE model (Huber, Shiffrin, Lyle, & Ruys, Psychological Review 108:149?C182, 2001) predicts this interaction by positing that prime features are confused with target features and that evidence regarding the prime features is discounted less for short primes and more for long primes, when both are compared with the optimal level. In the present study, we augmented the typical short-term priming experiment by adding flankers that appeared simultaneously with the target and remained for a short or long duration. In the experiment, we replicated previous priming effects and produced novel effects of flanker duration. ROUSE accounted for both the priming and flanker findings with the previously posited processes, but with different quantitative parameters for flankers: Relative to optimal levels of discounting, all flanker features were underdiscounted, but longer flankers were discounted more than short flankers.
