Negative priming with masked distractor-only prime trials: awareness moderates negative priming

The literature yields inconsistent evidence for negative priming (NP) following masked distractor-only prime trials. We contrast two different hypotheses on the inconsistent findings: one - which is most compatible with the temporal discrimination theory - that relates the sign of priming effects to the absence vs. presence of prime awareness and one -which is most compatible with the inhibition and episodic retrieval accounts - that relates the sign of priming effects to the prime event being categorized as a to-be-attended vs. to-be-ignored event. In two experiments, it turned out that participants' awareness of the masked stimuli caused the different results (with participants being not aware of the primes showing NP), whereas the factor prime color = probe target color vs. prime color = probe distractor color (i.e., the prime contains the to-be-attended vs. the to-be-ignored signal) did not moderate NP. These findings are discussed with regard to theories of negative priming and the debate on conscious vs. unconscious perception.     

Classical fear conditioning in the anxiety disorders: a meta-analysis

Fear conditioning represents the process by which a neutral stimulus comes to evoke fear following its repeated pairing with an aversive stimulus. Although fear conditioning has long been considered a central pathogenic mechanism in anxiety disorders, studies employing lab-based conditioning paradigms provide inconsistent support for this idea. A quantitative review of 20 such studies, representing fear-learning scores for 453 anxiety patients and 455 healthy controls, was conducted to verify the aggregated result of this literature and to assess the moderating influences of study characteristics. Results point to modest increases in both acquisition of fear learning and conditioned responding during extinction among anxiety patients. Importantly, these patient-control differences are not apparent when looking at discrimination studies alone and primarily emerge from studies employing simple, single-cue paradigms where only danger cues are presented and no inhibition of fear to safety cues is required.     

Single Session Psychology Clinic for Parents of Children with Autism Spectrum Disorder: A Feasibility Study

Children are being diagnosed with autism spectrum disorder at much higher rates than in the past, with the increasing rates arising primarily from the broadened diagnostic criteria and increased public and professional awareness of the disorder. In turn, this has resulted in increased demands for psychological services, which many service providers struggle to meet. Single session clinics are an innovative form of intervention which can facilitate quick access to psychological services, without the burden of lengthy waiting times. This feasibility study examined the nature of presenting problems, attendance rates and parental satisfaction with a single session clinic for parents of children with autism spectrum disorder. The service offers short one-to-one consultation with a psychologist and sessions can be booked up to one month in advance. The single session clinic was developed to provide individual intervention to families within the constraints of an overwhelmed service. Good attendance rates and relatively high satisfaction suggest the single-session consultation for parents of children with autism spectrum disorder is an acceptable form of service. Limitations include the a need for more detailed evaluation of the impact of the sessions on both parental anxiety and child outcomes, and to identify more clearly who may benefit most from this model.     

Dissociation of binding and learning processes

A single encounter of a stimulus together with a response can result in a short-lived association between the stimulus and the response [sometimes called an event file, see Hommel, Müsseler, Aschersleben, & Prinz, (2001) Behavioral and Brain Sciences, 24, 910–926]. The repetition of stimulus–response pairings typically results in longer lasting learning effects indicating stimulus–response associations (e.g., Logan & Etherton, (1994) Journal of Experimental Psychology: Learning, Memory, and Cognition, 20, 1022–1050]. An important question is whether or not what has been described as stimulus–response binding in action control research is actually identical with an early stage of incidental learning (e.g., binding might be seen as single-trial learning). Here, we present evidence that short-lived binding effects can be distinguished from learning of longer lasting stimulus–response associations. In two experiments, participants always responded to centrally presented target letters that were flanked by response irrelevant distractor letters. Experiment 1 varied whether distractors flanked targets on the horizontal or vertical axis. Binding effects were larger for a horizontal than for a vertical distractor-target configuration, while stimulus configuration did not influence incidental learning of longer lasting stimulus–response associations. In Experiment 2, the duration of the interval between response n – 1 and presentation of display n (500 ms vs. 2000 ms) had opposing influences on binding and learning effects. Both experiments indicate that modulating factors influence stimulus–response binding and incidental learning effects in different ways. We conclude that distinct underlying processes should be assumed for binding and incidental learning effects.

Do Equal Rights for a Minority Affect General Life Satisfaction?

While previous research examines how institutions matter for general life satisfaction and how specific institutions embodying equal rights for gay people matter for the life satisfaction of gays, we combine these two issues to analyze how the latter type of institutions relates to general life satisfaction. The question is how people in general are affected by laws treating everyone equally irrespective of sexual orientation. We find that legal recognition of partnership, marriage and adoption rights, as well as an equal age of consent, relate positively to general life satisfaction. Consequently, same-sex marriage and similar reforms come at no “welfare” cost to society at large—if anything, the opposite appears to hold. We further build on previous research showing positive effects of economic freedom on happiness and on tolerance towards gay people and interact our rights measure with economic freedom. This reveals that the positive effect on general happiness of equal rights mainly appears in countries with low economic freedom. This likely follows because minority rights are perceived to indicate openness to much-desired reforms in other areas.
