Theory of mind and joint action in Parkinson’s disease

It has been suggested that the Theory of Mind (ToM) may rely on more basic processes of social cognition, such as action control (e.g., joint action), even if little is known about this relationship. The relationship between ToM and joint action can be studied in patients with Parkinson’s disease (PD), because they are characterized not only by a deficit in ToM (and in its cognitive and affective subcomponents) but also by a deficit in the inhibition of competing responses. Sixty PD patients and 60 matched healthy controls (HCs) performed a go/no-go Flanker task in both joint and individual conditions. Cognitive (Advanced Test or AT) and affective (Emotion Attribution Task or EAT) ToM also were measured. Thirty-five PD patients and matched HCs also performed the standard Flanker task, as a control measure. In patients, only individuals with high AT scores exhibited a joint Flanker effect, whereas in HCs the joint effect was found irrespectively of AT score. Patients with low EAT scores showed a greater interference effect than patients with high scores, whereas the opposite pattern was found for HCs. In regression analysis AT and EAT scores predicted the Flanker effect in the joint condition only. In the standard task, both groups showed a Flanker effect. The role of different fronto-striatal circuits, especially in PD patients, could explain the different involvement of cognitive and affective ToM in joint tasks. The Flanker effect is discussed considering the referential coding account and the attention-focus account as possible candidates to explain joint action effects.     

Different Words for the Same Concept: Learning Collaboratively From Multiple Documents

This study investigated how varying the lexical encodings of technical terms in multiple texts influences learners' dyadic processing of scientific-related information. Fifty-seven pairs of college students read journalistic texts on depression. Each partner in a dyad received one text; for half of the dyads the partner's text contained different lexical encodings of the same concepts; for the other half the lexical encodings and texts were identical. They then read a case report on first signs of depression. Communicating via a chat room, each dyad had to write a causal diagnosis and suggest a treatment. Results showed that dyads in the different-encoding condition explicitly elaborated the meaning of technical terms more often, produced more differentiated answers, and acquired more knowledge. It is concluded that deliberately switching different words for the same underlying content, and engaging students in discussion of that content, influences learners' discourse and promotes scientific/conceptual understanding.     

La investigación en Psicología Diferencial Cognoscitiva: estrategias de segunda generación

Resumen

En este artículo se exponen las estrategias de segunda generación que, dentro del ámbito de investigación de la Psicología Diferencial Cognosátiva, se consideran más representativas, a saber: el análisis componencial, el análisis factorial confirmatorio, y el análisis de rasgo latente. Estas estrategias de investigación en Psicología Diferencial Cognoscitiva tienen, en contraste con las estrategias de primera generación, un dominio de aplicación más amplio. Tanto las estrategias de primera como las de segunda generación pueden ser utilizadas conjuntamente, siempre de acuerdo a las consideraáones teóricas de interés que trate de analizar el investigador.     

Reprint of: stuttering treatment control using P300 event-related potentials

Positron emission tomography studies during speech have indicated a failure to show the normal activation of auditory cortical areas in stuttering individuals. In the present study, P300 event-related potentials were used to investigate possible effects of behavioral treatment on the pattern of signal amplitude and latency between waves. In order to compare variations in P300 measurements, a control group paired by age and gender to the group of stutterers, was included in the study. Findings suggest that the group of stutterers presented a significant decrease in stuttering severity after the fluency treatment program. Regarding P300 measurements, stutterers and their controls presented results within normal limits in all testing situations and no significant statistical variations between pre and post treatment testing. When comparing individual results between the testing situations, stutterers presented a higher average decrease in wave latency for the right ear following treatment. The results are discussed in light of previous P300 event-related potentials and functional imaging studies with stuttering adults.Educational objectives: The reader will learn about and be able to describe the: (1) use of P300 event-related potentials in the study of stuttering; (2) differences between stuttering and non-stuttering adults; and (3) effects of behavioral fluency treatment on cerebral activity in stuttering speakers.     

Development of a therapists’ self-report measure of pluralistic thought and practice: the Therapy Pluralism Inventory

This study aimed to develop a self-report measure of pluralistic thought and practice. Following pilot development, a 23-item inventory was placed on an online survey site, and 474 participants satisfactorily completed the measure. Respondents were trainee or qualified therapists, predominantly female, based in the UK, and of a humanistic or integrative/eclectic orientation. A principal components analysis resulted in two scales, Pluralistic Philosophy and Pluralistic Practice, which had good internal consistency (Cronbach’s α?=?.72 and .80, respectively). Confirmatory factor analysis showed good model fit for this two factor solution. The Therapy Pluralism Inventory (TPI) has potential for use in training and research, although additional validity and normative data are needed.     

Perceptions of Sexual Intent: The Impact of Condom Possession

This study examined whether knowing that a victim of a sexual assault was carrying a condom influenced perceptions of her sexual intention and subsequent judgments of the sexual assault. Participants  ( N = 165)  read a vignette describing a date that culminated in an alleged sexual assault. Condom possession (carrying a condom, not carrying a condom) of both the female and male target was systematically varied. When the woman was carrying a condom, the woman was perceived as more sexually willing and the sexual assault claim perceived as less valid. In contrast, the male target's condom possession had little impact on judgments.     

Marian Images: Madonna and Hodigitria

The Madonna of Western religious art and the articulation of Marian theology is enunciated in Kathleen C. Ford's piece entitled Portrait of Our Lady. This paper is a companion piece focusing on the Hodigitria, Mother of God, an Eastern liturgical icon and its theological and psychological influence on the clinical treatment of a young woman. The client's recurrent turtle metaphor is discussed for clinical significance. In both portraits, Madonna and Hodigitria, the centrality of the mother image is essential. Kathleen emphasized the influence of the Great Mother Archetype in art and religion and the ancillary theme of containing and contained. The emphasis in this companion paper is the mother image as theologically and psychologically relational, communal, interpathic and companioning.     

Stigma, Culture, and HIV and AIDS in the Western Cape, South Africa: An Application of the PEN-3 Cultural Model for Community-Based Research

HIV- and AIDS-related stigma has been reported to be a major factor contributing to the spread of HIV. In this study, the authors explore the meaning of stigma and its impact on HIV and AIDS in South African families and health care centers. They conducted focus group and key informant interviews among African and Colored populations in Khayelitsha, Gugulethu, and Mitchell's Plain in the Western Cape province. The audio-recorded interviews were transcribed and coded using NVivo. Using the PEN-3 cultural model, the authors analyzed results showing that participants' shared experiences ranged from positive/nonstigmatizing, to existential/unique to the contexts, to negative/stigmatizing. Families and health care centers were found to have both positive nonstigmatizing values and negative stigmatizing characteristics in addressing HIV/AIDS-related stigma. The authors conclude that a culture-centered analysis, relative to identity, is central to understanding the nature and contexts of HIV/AIDS-related stigma in South Africa.     

Predicting post-event processing in social anxiety disorder following two prototypical social situations: State variables and dispositional determinants

This study investigated self-reported state (anxiety, physical symptoms, cognitions, internally focused attention, safety behaviors, social performance) and trait (social anxiety, depressive symptoms, dysfunctional self-consciousness) predictors of post-event processing (PEP) subsequent to two social situations (interaction, speech) in participants with a primary diagnosis of social anxiety disorder (SAD) and healthy controls (HC). The speech triggered significantly more intense PEP, especially in SAD. Regardless of the type of social situation, PEP was best predicted by situational anxiety and dysfunctional cognitions among the state variables. If only trait variables were considered, PEP following both situations was accounted for by trait social anxiety. In addition, dysfunctional self-consciousness contributed to PEP-speech. If state and trait variables were jointly considered, for both situations, situational anxiety and dysfunctional cognitions were confirmed as the most powerful PEP predictors above and beyond trait social anxiety (interaction) and dysfunctional self-consciousness (speech). Hence, PEP as assessed on the day after a social situation seems to be mainly determined by state variables. Trait social anxiety and dysfunctional self-consciousness also significantly contribute to PEP depending on the type of social situation. The present findings support dysfunctional cognitions as a core cognitive mechanism for the maintenance of SAD. Implications for treatment are discussed.
