Group cognitive-behavioral therapy for anxiety in a clinic setting: does child involvement predict outcome?

The current study examined the relationship between child involvement and treatment outcome in a group cognitive–behavioral treatment (GCBT) program for children with anxiety, using an adapted version of the Child Involvement Rating Scale (CIRS). Thirty-four children with a primary diagnosis of an anxiety disorder, referred for outpatient treatment at a hospital, and their parents participated in a manualized 12-session GCBT program. The Multidimensional Anxiety Scale for Children (MASC), administered at pretreatment, posttreatment, and at 4-month follow-up, served as the outcome measure. The psychometric properties of the adapted CIRS were good. Early involvement (EI) was calculated as the average score from Sessions 1 to 6 and late involvement (LI), the average score from Sessions 7 to 12. EI predicted lower MASC scores at posttreatment, after controlling for pretreatment MASC scores and for LI, B = – 1.05, t(3) = – 2.34, p < .05. EI did not predict outcomes at follow-up. Results were replicated using the original CIRS measure. Exploratory analyses suggested that the relationship between LI and treatment outcomes was moderated by medication. Involvement in therapy prior to exposures might be an important predictor of posttreatment outcomes in GCBT in a community setting.     

Prospective memory and aging: preserved spontaneous retrieval,but impaired deactivation,in older adults

Prospective remembering is partially supported by cue-driven spontaneous retrieval processes. We investigated spontaneous retrieval processes in younger and older adults by presenting prospective memory target cues during a lexical decision task following instructions that the prospective memory task was finished. Spontaneous retrieval was inferred from slowed lexical decision responses to target cues (i.e., intention interference). When the intention was finished, younger adults efficiently deactivated their intention, but the older adults continued to retrieve their intentions. Levels of inhibitory functioning were negatively associated with intention interference in the older adult group, but not in the younger adult group. These results indicate that normal aging might not compromise spontaneous retrieval processes but that the ability to deactivate completed intentions is impaired.     

How information guides movement: intercepting curved free kicks in soccer

Previous studies have shown that balls subjected to spin induce large errors in perceptual judgments ( [Craig et al., 2006] and [Craig et al., 2009] ) due to the additional accelerative force that causes the ball’s flight path to deviate from a standard parabolic trajectory. A recent review however, has suggested that the findings from such experiments may be imprecise due to the decoupling of perception and action and the reliance on the ventral system (van der Kamp, Rivas, van Doorn, & Savelsbergh, 2008). The aim of this study was to present the same curved free kick trajectory simulations from the perception only studies ( [Craig et al., 2006] and [Craig et al., 2009] ) but this time allow participants to move to intercept the ball. By using immersive, interactive virtual reality technology participants were asked to control the movement of a virtual effector presented in a virtual soccer stadium so that it would make contact with a virtual soccer ball as it crossed the goal-line. As in the perception only studies the direction of spin had a significant effect on the participants’ responses with significantly fewer balls being intercepted in the spin conditions when compared to no-spin conditions. A significantly higher percentage of movement reversals for the spin conditions served to highlight the link between information specifying ball heading direction and subsequent movement. The coherence of the findings for both the perception and perception/action study are discussed in light of the dual systems model for visual processing.     

How to measure post-error slowing: A confound and a simple solution

In many response time tasks, people slow down after they make an error. This phenomenon of post-error slowing (PES) is thought to reflect an increase in response caution, that is, a heightening of response thresholds in order to increase the probability of a correct response at the expense of response speed. In many empirical studies, PES is quantified as the difference in response time (RT) between post-error trials and post-correct trials. Here we demonstrate that this standard measurement method is prone to contamination by global fluctuations in performance over the course of an experiment. Diffusion model simulations show how global fluctuations in performance can cause either spurious detection of PES or masking of PES. Both confounds are highly undesirable and can be eliminated by a simple solution: quantify PES as the difference in RT between post-error trials and the associated pre-error trials. Experimental data are used as an empirical illustration.     

Transient state-dependent fluctuations in anxiety measured using STAI, POMS, PANAS or VAS: a comparative review

Abstract Several psychometric instruments can be used to measure state-dependent variations in anxiety, including the State-Trait Anxiety Inventory (STAI), the Profile of Mood States (POMS), the Positive and Negative Affect Schedule (PANAS) and the Visual Analog Scales (VAS). Each of these instruments rests on specific theoretical assumptions about the construct of state anxiety, and has been widely used for this purpose in different research domains. However, it remains difficult to determine what may be the specificities of these four instruments, when the goal is to measure transient state-dependent variations in anxiety. In this work, we provide a systematic and comparative literature review of studies which have explored rapid fluctuations (i.e., test-retest intervals not exceeding 24 hours) in state anxiety by means of these specific instruments. Almost 200 studies were eventually included in our review. This comparative review confirms that, despite some disparities and specificities, each of these four instruments provides a reliable measure to capture rapid state-dependent variations in anxiety, although they have been used in non-overlapping research domains or experimental contexts.     

The impact of emotion on prospective memory and monitoring: No pain, big gain

The emotionally enhanced memory effect is robust across studies of retrospective memory, with heightened recall for items with emotional content (e.g., words like ??murder??) relative to neutral items (e.g., words like ??envelope??). Only a handful of studies have examined the influence of emotion on prospective memory (PM), with mixed results. In some cases emotion enhances PM, and in others it impairs PM. Interpretation of these findings is clouded by methodological differences across studies and by the fact that, to date, no study has examined the impact of emotion on PM monitoring. In our study, we assessed PM performance when PM targets were neutral, negative, and positive, and also investigated monitoring across these different PM target types. Participants showed heightened PM performance for positive and negative relative to neutral targets, yet there was no evidence of additional monitoring for emotional targets. In fact, measures of monitoring were significantly reduced when the PM targets were emotional rather than neutral. Our findings suggest that it is possible to boost PM performance in a focal task using emotional cues, and that the use of emotional cues reduces the need for monitoring.

We describe the hardware and the software, the general development plan, and some problems that should be considered by others who may plan to develop a similar laboratory.     

Wernicke''s aphasia in a 10-year-old boy

We report the case of a ten-year-old boy, who, after herpes simplex encephalitis, presented a sensory aphasia having much in common with Wernicke's aphasia in adults. The genesis of neologisms appeared very similar to the mechanisms described by Buckingham and Kertesz (1974, Brain and Language, 1, 43-61). The findings are discussed in the light of theories of hemispheric specialization and of age-related semiologies.     

Qualitative and quantitative considerations in encoding difficulty effects

We hypothesized that the effects of encoding difficulty on the memorability of verbal material would depend on both the type of processing induced by the difficulty manipulation and the type of processing afforded by the material. We predicted that if the processing induced by encoding difficulty were complementary to the processing afforded by the material, then difficulty would enhance recall more so than if the processing induced by the two sources were redundant. These expectations were tested by requiring subjects to process either a structured or an unstructured word list with either a sorting task or a pleasantness rating task; the difficulty of each orienting task was also manipulated. We assumed that sorting and pleasantness rating required primarily relational and individual-item processing, respectively, and that the structured and unstructured word lists afforded relational and individual-item processing, respectively. These assumptions were supported by clustering in free recall and by recognition performance. The primary finding was that difficult sorting increased recall only for the unrelated list, whereas difficult pleasantness judgments increased recall most robustly for the related list. These results support the present framework and help illuminate the boundary conditions of the “difficulty effect.”     

Propositions pour un positivisme

Summary The author tries to specify a philosophical attitude which could be considered a form of Positivism, but this does not necessarily mean that it coincides with the doctrine of Auguste Comte or with that of the Vienna Circle.In order to facilitate the exposition the author formulates eight theses whose abrupt character is merely a consequence of the manner of presentation and by no means a manifestation of dogmatism.Eachdatum presents itself as finite experience (1) which is organized with the help ofsymbols, either on the level of perception or on the level of language (2). Inside the perception itself a reduction of experience which is essentially pragmatic first constitutes thephenomena (3). Theobject which is constituted by science on the basis of the phenomena is merely structural and always delimited (4). Its constitution is unceasingly revisable and it never corresponds to an alleged essence of reality.What is here called dialectic never consists in a set of rules governing a movement of phenomena, objects, or ideas; it is a general, historical movement of experience itself, taken as a whole, and the specific movement of the symbolic statements which inform it. One should not confuse it with a kind of general logic, nor with a so-called science of totalities (5). Logic explains the rules of the symbolic systems (6), andscience is the mediate determination of objects by means of the symbolism, and is not an immediate determination of reality (7). It constructs coherent and effective models of phenomena.As far asphilosophy is concerned, it wishes to interpret experience as a totality, not-withstanding experience's finitude as datum (8). Thus it is radically distinguished from science in that philosophy does not intend to construct models, but to explain the meanings of the phenomena and, in general, of experience. That is why the category of truth taken in a rigorous sense does not apply to philosophy's statements.
