Simultaneous execution of two cognitive operations : Evidence from a continuous updating paradigm
(2004)
This editorial summarizes the currant state of development of guidelines for the assessment and treatment of mental disorders in children and adolescents. The aims of guidelines and criteria for the quality of guidelines are discussed. This special issue intends to be a starting point for the development of guidelines for psychological and psychotherapeutic disciplines in the German-speaking countries
Assessing individual differences in achievement motivation with the Implicit Association Test
(2004)
The authors examined the validity of an Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998) for assessing individual differences in achievement tendencies. Eighty-eight students completed an IAT and explicit self- ratings of achievement orientation, and were then administered a mental concentration test that they performed either in the presence or in the absence of achievement-related feedback. Implicit and explicit measures of achievement orientation were uncorrelated. Under feedback, the IAT uniquely predicted students' test performance but failed to predict their self-reported task enjoyment. Conversely, explicit self-ratings were unrelated to test performance but uniquely related to subjective accounts of task enjoyment. Without feedback, individual differences in both performance and enjoyment were independent of differences in either of the two achievement orientation measures. (C) 2004 Elsevier Inc.

During reading, our eyes perform complicated sequences of fixations on words. Stochastic models of eye movement control suggest that this seemingly erratic behaviour can be attributed to noise in the oculomotor system and random fluctuations in lexical processing. Here, we present a qualitative analysis of a recently published dynamical model [Engbert et al., 2002] and propose that deterministic nonlinear control accounts for much of the observed complexity of eye movement patterns during reading. Based on a symbolic coding technique we analyze robust statistical features of simulated fixation sequences
An outline of evidence-based guidelines for the assessment and treatment of depressive disorders in childhood and adolescence is presented. Depressive disorders in children and adolescents are marked by core symptoms similar to those seen in adults, although symptom expression varies greatly with developmental stage. These disorders are common, especially in adolescence, chronic, and recurrent, and are associated with comorbid conditions such as anxiety disorders, conduct disorders, and substance use disorders. Effective treatment approaches for the prevention of depressive disorders and the acute treatment of mild and moderate depressive disorders are available. The psychotherapeutic interventions of choice are currently cognitive behavioral therapy (CBT) and interpersonal therapy (IPT). The antidepressants of choice are currently selective serotonin reuptake inhibitors (SSRI). Especially on relapse prevention and the evaluation of the combination of psychotherapy with antidepressant medication further studies are necessary
