Emotional stimuli modulate readiness for action: A transcranial magnetic stimulation study

Emotional stimuli may prime the motor system and facilitate action readiness. Direct evidence for this effect has been shown by recent studies using transcranial magnetic stimulation (TMS). When administered over the primary motor cortex involved in responding, TMS pulses elicit motor-evoked potentials (MEPs) in the represented muscles. The amplitudes of these MEPs reflect the state of corticospinal excitability. Here, we investigated the dynamic effects of induced emotions on action readiness, as reflected by corticospinal excitability. Subjects performed a choice task while viewing task-irrelevant emotional and neutral pictures. The pattern of MEP amplitudes showed a typical increase as the TMS pulse was presented closer in time to the imminent response. This dynamic pattern was amplified by both pleasant and unpleasant emotional stimuli, but more so when unpleasant pictures were viewed. These patterns present novel evidence in support of the notion that emotional stimuli modulate action readiness.     

Predicting preference for items during periods of extended access based on early response allocation

Top‐ranked items were identified during 30‐min free‐operant preference assessments for 9 individuals. Data from each session were analyzed to identify the item (a) that was engaged with first in each session and (b) to which the most responding was allocated after 5 min, 10 min, 15 min, 20 min, and 25 min had elapsed in each session. The results indicated that the first‐engaged item and the 5‐min high‐allocation item predicted the top‐ranked item in 55% and 62% of the sessions, respectively. The results also showed that engagement with the top‐ranked item from the first session decreased across subsequent sessions for 6 of the 9 participants. The implications of the results for brief versus extended stimulus preference assessments are discussed.     

Displaying and Deciding Substructural Logics 1: Logics with Contraposition

Many logics in the relevant family can be given a proof theory in the style of Belnap's display logic (Belnap, 1982). However, as originally given, the proof theory is essentially more expressive than the logics they seek to model. In this paper, we consider a modified proof theory which more closely models relevant logics. In addition, we use this proof theory to show decidability for a large range of substructural logics.     

And the dish ran away with the spoon: a hodgepodge of reflections,as rigorous as they are rambling,on the true subject

In this article, the topic of ‘the true subject’ is explored in terms of a dialectical mode thinking which is in keeping with Jung's great insight concerning psychology's lack of an Archimedean vantage‐point distinct from its topics and subject matters. Evocative and expository, the emphasis is upon the performative poetics of such thinking within the sphere of our soul‐making. The interpretative mode of practice presented in the article is richly illustrated with examples from Biblical texts, literary images, and proverbial sayings, as well as from the sur‐real of nursery rhyme and the genre of the murder mystery. Essential insights of Jung's concerning the infinite and the finite as dimensions of self are revisited in terms of that contemporary trend of Jungian thought known as psychology as the discipline of interiority.     

Going backstage: a psychoanalytically informed study with amateur musicians in adult mental health services

Many mental health service users engage in potentially therapeutic amateur music practice, though the role of this in the maintenance of mental health is largely unexplored. The application of psychoanalytic ideas to music-playing gives suggestions for how this activity could helpfully sublimate distress. For this study, six men who attend adult mental health services and play a musical instrument took part in three unstructured hour-long interviews. The material was analysed with a psychoanalytically informed method. Four inter-related themes emerged: ‘Left on the outside’; ‘Playing and linking’; ‘A beautiful gift to myself’; and ‘Frustrating play’. In the lives of these amateur musicians, music’s role as a transitional object and means of containing distress is explored. There is discussion of the narcissistic function of music and the dynamics around music as an exhibitionistic act. The value of paying attention to music in the life of a patient is considered.     

The Effects of a PETTLEP Imagery Intervention on Learners' Coincident Anticipation Timing Performance

Little research has examined how imagery effects learners' acquisition of motor tasks requiring coincident anticipation timing (CAT). CAT is a fundamental component of hitting, passing, and receiving required in several sports. The purpose of the current study was to examine the effects of a PETTLEP imagery intervention on learners' CAT performance using a Bassin Anticipation Timer. Fifty-six participants (M = 20.61 years, SD = 2.48) were randomly assigned into one of four training groups: physical practice (PP), imagery practice (IP), imagery practice + physical practice (IP +PP), or a control (CON) group. The study consisted of three phases: pretest, intervention, and a posttest. Results revealed that the PP and IP+PP groups had significantly lower absolute timing error compared to the CON group on the posttest. The IP+PP group was the only group to have lower variable error compared to the CON group on the posttest. Results extend prior research by demonstrating that imagery combined with physical practice can benefit the learning of a CAT task and that imagery alone may not assist learners in acquiring tasks requiring CAT. Results are congruent with prior research demonstrating that imagery is most effective when combined with physical practice.     

Utilizing Participatory Mapping and GIS to Examine the Activity Spaces of Homeless Youth

Although previous studies have informed our understanding of certain aspects of youth homelessness, few studies have critically examined the spatial and social environments utilized by youth as they navigate life on the streets. This study employed participatory mapping and Geographic Information Systems (GIS) to examine the activity spaces of homeless youth as they relate to sense of community and psychological well‐being. Participants were 28 youth experiencing homelessness in Portland, Oregon, USA. Results suggest that youth engage most frequently in service‐related activities, and their activity participation is significantly associated with sense of community and psychological well‐being. The utility of innovative participatory methods for better understanding the diverse experiences of homeless youth is discussed alongside examination of their practical implications.     

Sociology as a Naïve Science: Alfred Schütz and the Phenomenological Theory of Attitudes

Alfred Schütz is often credited with providing sociology with a firm ground derived from phenomenology of science and justifying it as a science operating within natural attitude. Although his project of social science draws extensively on Edmund Husserl’s theory of attitudes, it would be incorrect to assume that Schütz shares with the founder of phenomenology his conception of science. This paper compares Husserl’s and Schütz’s views on the structure and meaning of science and traces the roots of their radical divergence. Whereas Husserl increasingly emphasises the importance of phenomenological reduction for the genuine human science, Schütz eventually rejects reduction and restricts the social science to a specific system of relevancies within the reality of the lifeworld. This paper presents the argument that Schütz’s conception eliminates the possibility of a phenomenological justification of social science, as it implies that there are no rationally justifiable grounds to pursue science. In this way, Schütz’s views substantially differ from the phenomenological theory of science and become open to the phenomenological critique of naivety.
