Effects of unit formation on the perception of a changing sound

The effects of subunit formation on adult listeners' ability to notice changes in a continuous spectral gradient of sound were studied. Results of this experiment support the idea that the auditory system processes information differently within a unit, and that this processing does not occur unless the perceptual system detects unit boundaries. In this experiment, silences were inserted into a continuously changing sound to cause the formation of short units. Listeners noticed the change earlier in conditions with silences inserted than in to conditions where the transition was either unbroken or broken by loud noise bursts. Results are discussed in terms of two processes, one that accentuates stimulus properties present at moments of onset and offset, and a second that uses onsets and offsets to signal the beginnings and ends of units and reduces the change perceived within units.     

Is cleanliness next to abstinence? The effect of cleanliness priming on attitudes towards harm reduction strategies for people with substance use disorders

Can exposure to a cleanliness prime affect moral judgements towards harm reduction strategies (HRS) for individuals with substance use disorders? Our research examined (a) the effect of a cleanliness prime on attitudes towards HRS and (b) whether this effect would be attenuated by a brief educational presentation. Participants were randomly assigned to a priming condition and an educational presentation condition. Results demonstrated that (a) the cleanliness prime did not shift attitudes towards HRS, however, (b) the educational presentations significantly shifted attitudes to be more positive after the Harm Reduction presentation and more negative after the Healthy Living presentation. The literature on priming is mixed and our results support a growing body of research challenging the robustness of cleanliness priming and also demonstrates that brief presentations can change attitudes. Our research has implications for education on the benefits of HRS in reducing disease transmission, refuse in the community, and overdose deaths.     

Cognitive-behavioral treatment of high anger drivers

Relaxation and cognitive-relaxation interventions were compared to a no treatment control in the treatment of high anger drivers. The cognitive portion of the cognitive-relaxation condition adapted the style of Beck's cognitive therapy, particularly use of Socratic questions and behavioral experiments and tryouts, to driving anger reduction. Both interventions lowered indices of driving anger and hostile and aggressive forms of expressing driving anger and increased adaptive/constructive ways of expressing driving anger. The cognitive-relaxation intervention also lowered the frequency of risky behavior. Both interventions lowered trait anger as well. Limitations and implications for treatment and research were discussed.

Caution! Warnings as a Useless Countermeasure to Reduce Overconfidence? An Experimental Evaluation in Light of Enhanced and Dynamic Warning Designs

People often display excessive overconfidence when providing interval estimates, which biases decision‐making. Research has investigated the various measures to effectively reduce overconfidence, and the use of warnings has subsequently been considered to have a negligible reduction effect. We demonstrate with two separate experiments that the impact of warnings has to be reviewed in light of dynamic warning designs and cognitive warning process models. In experiment 1, in contrast to previous studies that only used unstructured warnings, we implement a warning incorporating some core elements of a structured warning design based on research in the fields of human factors and ergonomics. Furthermore, accounting for recent developments in the warning literature, we distinguish between static and dynamic warning design. In experiment 2, we examine the effectiveness of different elements of dynamic warnings. We show that a significantly higher reduction of overconfidence can be achieved by combining a structured warning content with a dynamic stimulus change to increase the warning's noticeability.

Evidence of blocking with geometric cues in a virtual watermaze

Three computer based experiments, testing human participants in a non-immersive virtual watermaze task, used a blocking design to assess whether two sets of geometric cues would compete in a manner described by associative models of learning. In stage 1, participants were required to discriminate between visually distinct platforms. In stage 2, additional spatial information was provided by the shape or the color of the walls of the pool. In a test trial, the platforms were removed and the spatial knowledge acquired regarding the position of the platform was assessed. Experimental groups were compared against control groups which did not receive stage 1 training. The unique color of the correct platform, in Experiments 1 and 3, disrupted learning about the colored walls but not the geometry of the pool. In Experiment 2, the correct platform was identifiable from its position within the three platform array. Learning the relative position of the correct platform within the array disrupted learning about its position relative to the geometry of the pool, but not to the colored walls. The results suggest that learning the position of a goal in relation to the geometry of the environment can be blocked but only by an alternative geometric cue.     

选择性注意中意识与无意识过程分离的实验研究

以汉语单字词为材料,通过颜色来区分目标和分心物,采用过程分离程序,直接探讨了目标激活与分心物抑制和意识、无意识过程之间的关系。结果表明,（１）靶词充当分心物时,不仅意识过程存在的概率降低,无意识过程存在的概率也降低。这一结果说明,在选择性注意任务中,信息是有关还是无关,并不能分离意识和无意识过程;（２）靶词充当目标时,加工水平影响Ｐｃ,但不影响Ｐｕ,而靶词充当分心物时,加工水平既不影响Ｐｃ,也不影响Ｐｕ。因此,加工水平能否分离意识和无意识过程,依赖于靶词的作用或信息是否有关     

Effect of Training on Sensory Room and Cart Usage

In this study, the authors assess the effectiveness of education on the consistency of use of sensory rooms within a large mental health facility. Eleven staff and thirty-six clients received additional multimodal education in sensory strategies, the use of the sensory rooms on their assigned units, and the link between the rooms and clients' personal crisis intervention plans. Staff knowledge and room usage rates were analyzed pre- and post-training. The authors found statistically significant increases in staff knowledge post-training and increases in the use of the sensory rooms by study participants. The results support the effectiveness of training which uses hands-on, population-specific strategies.
