Interaction and representational integration: evidence from speech errors

We examine the mechanisms that support interaction between lexical, phonological and phonetic processes during language production. Studies of the phonetics of speech errors have provided evidence that partially activated lexical and phonological representations influence phonetic processing. We examine how these interactive effects are modulated by lexical frequency. Previous research has demonstrated that during lexical access, the processing of high frequency words is facilitated; in contrast, during phonetic encoding, the properties of low frequency words are enhanced. These contrasting effects provide the opportunity to distinguish two theoretical perspectives on how interaction between processing levels can be increased. A theory in which cascading activation is used to increase interaction predicts that the facilitation of high frequency words will enhance their influence on the phonetic properties of speech errors. Alternatively, if interaction is increased by integrating levels of representation, the phonetics of speech errors will reflect the retrieval of enhanced phonetic properties for low frequency words. Utilizing a novel statistical analysis method, we show that in experimentally induced speech errors low lexical frequency targets and outcomes exhibit enhanced phonetic processing. We sketch an interactive model of lexical, phonological and phonetic processing that accounts for the conflicting effects of lexical frequency on lexical access and phonetic processing.     

Positive emotions, emotional intelligence, and successful experiential learning

This study explored the role that positive emotions and emotional intelligence play in experiential learning. Students’ field practicum journals were analyzed using the Linguistic Inquiry and Word Count Program (LIWC) and a measure of emotional intelligence was obtained using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). Positive emotion words were robustly associated with almost all dimensions of supervisors’ ratings of students’ performance, but showed weak associations with students’ ratings of perceived benefits associated with their practicum experiences. Overall EI scores were correlated with several of the supervisor rating items and the Facilitating Thought and Managing Emotions subscales of the EI were robustly correlated with many of the student rating items. This study thus yielded a more differentiated view of the role of positive emotions and emotional intelligence in adaptive functioning and underscored the importance of using multiple informants to assess a complex construct such as successful experiential learning.     

Reversed mnemic neglect of self-threatening memories in dysphoria

Previous research has suggested that people have difficulties remembering information which is threatening to the self--an effect known as mnemic neglect. Three experiments are presented that examined mnemic neglect in dysphoria and whether dysphoric individuals show enhanced memory for self-threatening information. Pilot work determined that dysphoric participants rated central negative traits as more important than nondysphoric participants. In Experiment 1, dysphoric participants were found to have better memory for self-threatening information than nondysphoric participants. Enhanced recall of self-threatening memories was also found for unmodifiable (Experiment 2), and highly diagnostic (Experiment 3) self-threatening traits. The findings suggest that dysphoric participants show reversed mnemic neglect effects indicating enhanced access to negative information relating to the self.     

Influence of bilateral motor behaviors on flexible functioning: an embodied perspective

To examine the influence of bilateral motor behaviors on flexibility performance, two studies were conducted. Previous research has shown that when performing unilateral motor behavior that activates the affective and motivational systems of approach versus avoidance (arm flexion vs. extension), it is the congruence between laterality and motor activation that determines flexibility-rigidity functioning (Cretenet & Dru, 2009). When bilateral motor behaviors were performed, a mechanism of embodiment was revealed. It showed that the flexibility scores were determined by the match between the respective qualities of congruence of each of the unilateral motor behaviors performed. These results bring to light an overall embodied mechanism associated with the compatibility of the cognitive impact(s) of each motor behavior performed.     

Psychological and theological dynamics in an inpatient psychiatric chaplaincy group

This article describes the structure and goals of chaplaincy groups in an inpatient psychiatric setting. The article also explores their therapeutic benefits for patients and offers a theological framework for thinking about the conversations that unfolded in these groups. The article focuses in particular on the value of discussion and reflection in a group setting, the significance of receiving and answering questions, and the experience of participating in a simple ritual to name hopes.     

Using conditional discrimination training to produce emergent relations between coins and their values in children with autism

The current study evaluated the effects of conditional discrimination (listener) training with coins on the emergence of novel stimulus relations, textual behavior, tacts, and intraverbals. Two preschoolers with autism were taught 3 relations among coins, their names, and values. After initial training, 4 relations emerged for the first participant and 7 for the second participant, suggesting that this technology can be incorporated into educational curricula for teaching prerequisite money skills to children with autism.     

Influences of APOE ε4 and expertise on performance of older pilots

Little is known about how APOE ε4-related differences in cognitive performance translate to real-life performance, where training and experience may help to sustain performance. We investigated the influences of APOE ε4 status, expertise (FAA pilot proficiency ratings), and their interaction on longitudinal flight simulator performance. Over a 2-year period, 139 pilots aged 42-69 years were tested annually. APOE ε4 carriers had lower memory performance than noncarriers (p = .019). APOE interacted with Expertise (p = .036), such that the beneficial influence of expertise (p = .013) on longitudinal flight simulator performance was more pronounced for ε4 carriers. Results suggest that relevant training and activity may help sustain middle-aged and older adults' real-world performance, especially among APOE ε4 carriers.     

Factor Structure Validation of the Alcohol Dependence Scale in a Heavy Drinking College Sample

The prevalence of alcohol use disorders in college students necessitates that adequate measures exist to assess students for abuse and dependence. The Alcohol Dependence Scale (ADS) is a continuous measure of the severity of alcohol involvement found to have a unidimensional factor structure in clinical samples. The latent factor structure of the ADS in college drinkers has not been examined and this study sought to replicate unidimensionality. Heavy college drinkers (N = 343) completed the ADS. Performance was examined using confirmatory factor analysis (CFA) and exploratory factor analysis (EFA). The CFA did not support a single factor solution. Follow-up EFA revealed a two factor structure. The first, termed “Acute Excessive Drinking” consisted of relatively commonly endorsed items relating to loss of behavioral control, blackouts, and obsessive/compulsive drinking. The second, termed “Severe Withdrawal Symptoms,” consisted of relatively infrequently endorsed items relating to withdrawal symptoms. The ADS does not appear to have the same factor structure in college and clinical samples, making it inadvisable as a linear measure of alcohol problems within a college population.     

Parental Monitoring During Early Adolescence Deters Adolescent Sexual Initiation: Discrete-Time Survival Mixture Analysis

We used discrete-time survival mixture modeling to examine 5,305 adolescents from the 1997 National Longitudinal Survey of Youth regarding the impact of parental monitoring during early adolescence (ages 14–16) on initiation of sexual intercourse and problem behavior engagement (ages 14–23). Four distinctive parental-monitoring groups were identified and labeled as “High,” “Increasing,” “Decreasing,” and “Low”. About 68% of adolescents received a high level of parental monitoring from ages 14 to 16 (High), 6 and 9% respectively exhibited an accelerated (Increasing) and a decelerated trajectory (Decreasing), and 17% had consistently low parental monitoring (Low). Relative to participants in the Low group, adolescents in the High group delayed sexual initiation by 1.5 years. Males, relative to females, were more likely to have had a low trajectory of parental monitoring, and were more likely to initiate sexual intercourse before age 14. In contrast to White Adolescents, Hispanics and Blacks were less likely to receive High parental monitoring, and had a higher rate of early sexual initiation before age 14. The study demonstrates the temporal relationship of parental monitoring with adolescent sexual initiation from a longitudinal perspective. An increase of parental monitoring across ages is accompanied with a decrease of sexual risk. The continual high level of parental monitoring from ages 14 to 16 also mitigated the risk of engagement in substance use and delinquent behaviors from ages 14 to 23.     

Alexithymia in chronic urticaria patients

Alexithymia has been described as an important dimension in several medical and psychiatric diseases. Chronic urticaria (CU) is a chronic condition, in which treatment is difficult. Our aim is to determine the prevalence of alexithymia traits in patients with CU, and to identify the relationships between alexithymia and psychological variables and quality-of-life dimensions. Fifty-five sequential CU patients in a faculty ambulatory specialized consultation, with an average age of 44.92, were compared with 31 healthy volunteers. Both groups were studied by means of validated scales for alexithymia (Toronto Alexithymia Scale [TAS-20]), attachment (Adult Attachment Scale-R [AAS-R]), psychopathology (Brief Symptom Inventory [BSI]), personality dimensions (The NEO Five-Factor inventory [NEO-FFI]) and quality of life (Short Form-36 [SF-36]). The classification of CU reactions was obtained from the patient's history, physical examination, laboratory assessment and histopathologic findings. All the patients were under treatment with sedating H1-antihistamines, non-sedating H1-antihistamines combination of H1 and H2 blocker, 2 H1-antihistamines and 3 H1-antihistamines. High traits of alexithymia were found on CU patients (56.9%) as well as high symptom rates of anxiety. Alexithymia traits were significantly positively correlated with insecure attachment styles, with psychopathological symptoms, and with the defense mechanism turn against self. We also reported a significant negative correlation between alexithymia traits and the dimensions of quality of life. Insecure attachment styles were positively correlated with psychopathological symptoms and negatively correlated with quality of life. We did not find significant statistical correlations between alexithymia and clinical variables. CU patients present serious difficulty in dealing with emotion arousal. There is strong evidence of a psychosomatic specificity in CU, with marked alexithymic traits.
