Semantic relatedness among objects promotes the activation of multiple phonological codes during object naming

In a picture–word interference experiment the authors demonstrate that a semantic–categorical relation between a to-be-named target picture and a context picture promotes the phonological activation of the to-be-ignored context picture. No such phonological activation is observed if the objects are semantically unrelated. This finding gives further insight into the mechanisms that modulate the activation flow in the conceptual-lexical system during speech planning. In contrast to recent picture–picture interference studies, the results provide direct evidence that the phonological activation of a context object is dependent on its semantic processing.     

Do part–whole relations produce facilitation in the picture–word interference task?

Three experiments used the picture–word interference task to evaluate competing models of lexical access in spoken word production. Both the presence of a part–whole relation and association between the target and the interfering word were manipulated. Part terms associated with targets produced facilitation at early stimulus onset asynchronies (SOAs; –300?ms in Experiment 1, –300 and –150?ms in Experiment 3), but not at SOA 0?ms. Otherwise, part terms tended to produce interference, with unassociated part terms producing a significant semantic interference effect (SIE) at SOA of 0?ms in Experiment 1, and a similar trend in Experiment 3. Experiment 2 replicated the materials and procedure of Costa, Alario, and Caramazza (2005 Costa, A., Alario, F.-X., & Caramazza, A. (2005). On the categorical nature of the semantic interference effect in the picture-word interference paradigm. Psychonomic Bulletin & Review, 12(1), 125–131. doi:10.3758/BF03196357.2005-04938-012[Crossref], [PubMed], [Web of Science ®] , [Google Scholar], Experiment 2. On the categorical nature of the semantic interference effect in the picture–word interference paradigm. Psychonomic Bulletin & Review, 12(1), 125–131), yet failed to find any semantic facilitation at SOA 0?ms. We propose that these findings are consistent with lexical competition accounts of SIE but difficult to explain in terms of the plausibility of the interfering words as responses to the target.     

The internet and its role in the escalation of sexually compulsive behaviour

As increasing numbers of patients present with problems of compulsive use of internet sex and internet pornography, psychotherapists are challenged to develop models that address the powerful, and potentially disturbing effect of this stimulus. Internet sex does not just facilitate access to sexual materials but can act as a catalyst, affecting established defences and ego and superego functioning. Escalation in sexually compulsive behaviour, which affects a small proportion of those accessing online sex, may be thought of as a series of transitions: from casual to compulsive use, from compulsive use to illegal use, and from use of illegal pornography to contact offending. Drawing on clinical experience and the available research evidence, psychodynamic processes associated with movement through these transitions are considered. Internet sex has the potential to fuel manic defences, invites narcissistic and part-object relating, provides a vehicle for the expression and disowning of sadistic impulses and can potentially undermine superego functioning. The combined effect of these processes may lead to a breakdown of ego controls in vulnerable individuals.     

The Embodied Self. Movement and psychoanalysis

Increasing numbers of patients presenting problems with internet pornography have led to changes in the culture and practice of group analytic therapy at the Portman Clinic. The addictive element of this new form of artificial, sexual stimulation has to be recognised as part of the harm it produces. Group members spontaneously develop some of the principles and practice of established methods of addiction treatment, especially the 12-step programme, by helping each other manage their compulsion. This self-help function of the group coexists alongside the psychodynamic perspective, in which the meaning of harmful sexual behaviour is explored and understood. Certain individuals are more vulnerable to excessive use of pornography because of early developmental problems and current difficulties in their sexual relationships, resulting from internal conflicts about their sexuality. The group provides intimacy without sexualisation, primarily through a sibling transference. The therapist embodies an ability to think about the complexity of the sexual abuse that the pornography portrays. He or she works towards a truer perception of reality for group members, in which the false solutions of compulsive sexual behaviour are seen to be what they are: impediments to healthy development.     

Association between self-reported and performance-based navigational ability using internet-based remote spatial memory assessment

ABSTRACT

Traditionally, studies of spatial memory tend to utilise table-top tasks that focus on new spatial learning, however these in-lab procedures may not be reflective of real world spatial memory or navigation. This study investigated the relationship between self-rated navigation abilities and performance on a naturalistic Internet-based assessment of spatial memory for environments learned long ago. Results indicated that self-rated navigation ability was significantly associated with most of the remote spatial memory metrics. Familiarity with the geographical area tested, as well as frequency of visits, significantly predicted performance on the remote spatial memory measures. These results support the use of internet testing for performance-based navigation abilities in the assessment of remote spatial memory.     

Seeking support: An interpretative phenomenological analysis of an Internet message board for people with Complex Regional Pain Syndrome

In this article, we report on the findings of a qualitative inquiry into how an online message board for people who have Complex Regional Pain Syndrome (CRPS) was used by its members. All messages (and responses) posted on the CRPS message board over a 4-month period were collected retrospectively. The data were analysed using the method of Interpretative Phenomenological Analysis. Members used the message board to seek (and provide) support to those with CRPS, and also to express their emotions, feelings and experiences linked to their condition. The message board provided an important source of support for a patient group that can otherwise become isolated as a result of their mobility problems. Furthermore, the analysis revealed the unrealistic hopes that patients can hold concerning the anticipated outcomes of their treatment. This is an important issue for healthcare professionals to explicitly address when interacting with the patient group.     

Self-injury and readiness to recover: Preliminary examination of components of the stages of change model

The purpose of this study was to examine non-suicidal self-injury (NSSI) recovery through the lens of the transtheoretical model of stages of change. To do this, a content analysis of online posts about NSSI from 73 participants (M_age = 19.4; SD_age = 5.49) with a history or NSSI was performed. Specifically, two rubrics were used. The first examined stages of change and the other positive and negative views toward NSSI recovery. Results indicated that a preponderance of posts was in the precontemplation (39.7%) and contemplation (52.1%) stages. Individuals in the contemplation stage mentioned significantly more disadvantages than advantages to change compared to those in the precontemplation stage. Overall, the current study provides preliminary evidence for the utility of stages of change when conceptualizing NSSI recovery. Implications for research and practice are addressed.     

Selecting the Right Tool For the Job

There are competing ethical concerns when it comes to designing any clinical research study. Clinical trials of possible treatments for Ebola virus are no exception. If anything, the competing ethical concerns are exacerbated in trying to find answers to a deadly, rapidly spreading, infectious disease. The primary goal of current research is to identify experimental therapies that can cure Ebola or cure it with reasonable probability in infected individuals. Pursuit of that goal must be methodologically sound, practical and consistent with prevailing norms governing human subjects research. Some maintain that only randomized controlled trials (RCTs) with a placebo or standard-of-care arm can meet these conditions. We maintain that there are alternative trial designs that can do so as well and that sometimes these are preferable to RCTs.     

The contribution of prefixes to morphological processing of Spanish words

Three series of priming experiments were conducted to probe the morphological and phonological contributions to visual word recognition in Spanish. Prefixed, e.g., INCAPAZ (incapable), and pseudoprefixed, e.g., INDUSTRIA (industry) target words were presented for recognition following a prefixed, e.g., infeliz (unhappy), or pseudoprefixed, e.g., insulto (insult), prime starting with the same syllable as the target, at masked short or long stimulus onset asynchronies (SOAs). At long SOAs the recognition of prefixed targets was facilitated by prefixed primes and inhibited by pseudoprefixed ones, whereas both prefixed and pseudoprefixed primes facilitated the recognition at short SOAs. In contrast, the recognition of pseudoprefixed targets was unaffected by the kind of prime presented, even when we used pairs of words overlapping in syllables that cannot be prefixes in Spanish. These results support a special status for morphological elements in access to meaning in reading.     

The Influence of the Internet on the Psychosocial Predictors of Collective Action

The Internet has emerged as an important communication platform for the support of collective action, but little is known about how it influences the psychosocial motives for participation. Two quantitative studies were conducted within two different mobilizing contexts, in which offline collective actions were launched through computer‐mediated communication. We examined whether and how the frequency with which people participated in online political discussions moderated the effects of the psychosocial predictors of collective action, specifically politicized identity, anger, collective efficacy, and morality. Results showed that collective action intention was predicted by politicized identity only when participants reported a higher versus lower frequency of online discussion. However, anger did not predict collective action when people had the chance to express this emotion through a higher versus lower frequency of online discussion. Moreover, collective efficacy and morality supported collective action intention in participants who reported a higher versus lower frequency of online discussion. We theorize on how computer‐mediated communication, and its specific features, can be studied as a mobilizing context that influences the psychosocial motives to participate in collective action.
