Earwitness memory: distortions for voice pitch and speaking rate

In two experiments, memory distortions for voice pitch and speaking rate were examined. In both experiments, a significant distortion effect for voice pitch was observed, with listeners biased towards selecting voices lower in pitch than low‐pitch targets and selecting voices higher in pitch than high‐pitch targets. In contrast, for speaking rate there was little evidence for the production of memory distortions. The results are discussed in terms of transient surface properties of speech and how transience may be a factor in producing distortions. The results have implications for how errors arise during earwitness testimony for a suspect's voice. Copyright © 2009 John Wiley & Sons, Ltd.     

How accurately can older adults evaluate the quality of their text recall? The effect of providing standards on judgment accuracy

Adults have difficulties accurately judging how well they have learned text materials; unfortunately, such low levels of accuracy may obscure age‐related deficits. Higher levels of accuracy have been obtained when younger adults make postdictions about which test questions they answered correctly. Accordingly, we focus on the accuracy of postdictive judgments to evaluate whether age deficits would emerge with higher levels of accuracy and whether people's postdictive accuracy would benefit from providing an appropriate standard of evaluation. Participants read texts with definitions embedded in them, attempted to recall each definition, and then made a postdictive judgment about the quality of their recall. When making these judgments, participants either received no standard or were presented the correct definition as a standard for evaluation. Age‐related equivalence was found in the relative accuracy of these term‐specific judgments, and older adults' absolute accuracy benefited from providing standards to the same degree as did younger adults.

Older adults' decoding of emotions: role of dynamic versus static cues and age-related cognitive decline

Although age-related deficits in emotion recognition have been widely explored, the nature and scope of these deficits remain poorly understood. We conducted two experiments to examine whether these deficits are less pronounced when older adults evaluate dynamic compared with static images, and second, whether age-related cognitive decline exacerbates these deficits. Our results suggest that age-related cognitive decline exacerbates older adults' deficits in detecting anger, but only from static faces. Furthermore, older adults do not show emotion recognition deficits when evaluating global emotions from dynamic images of faces.     

Parental Interpersonal Sensitivity and Youth Social Problems: A Mediational Role for Child Emotion Dysregulation

We examined the relations between parental interpersonal sensitivity and youth social problems and explored the mediational role of child emotion dysregulation. Mothers (N = 42; M age = 39.38) and fathers (N = 41; M age = 39.38) of youth aged 7–12 (N = 42; M age = 9.12) completed measures of their own interpersonal sensitivity and reported on their child’s emotion regulation skills and social functioning. Maternal interpersonal sensitivity was positively associated with child social problems, and this relationship was fully mediated by child emotion dysregulation. A bootstrapping technique provided evidence for the significance of the mediation. For fathers, only the association between child emotion dysregulation and child social problems was significant. Our findings suggest one potential mechanism through which maternal behaviors relate to youth psychosocial functioning. Identification of such mechanisms contributes to the development of conceptual models of youth functioning and suggests specific targets for prevention and intervention efforts.     

Development of a Cognitive-Behavioral Intervention Program to Treat Anxiety and Social Deficits in Teens with High-Functioning Autism

Anxiety is a common co-occurring problem among young people with autism spectrum disorders (ASD). Characterized by deficits in social interaction, communication problems, and stereotyped behavior and restricted interests, this group of disorders is more prevalent than previously realized. When present, anxiety may compound the social deficits of young people with ASD. Given the additional disability and common co-occurrence of anxiety in ASD, we developed a manual-based cognitive-behavioral treatment program to target anxiety symptoms as well as social skill deficits in adolescents with ASD [Multimodal Anxiety and Social Skills Intervention: MASSI]. In this paper, we describe the foundation, content, and development of MASSI. We also summarize data on treatment feasibility based on a pilot study that implemented the intervention.     

Nonword repetition in children and adults: effects on movement coordination

Hearing and repeating novel phonetic sequences, or novel nonwords, is a task that taps many levels of processing, including auditory decoding, phonological processing, working memory, speech motor planning and execution. Investigations of nonword repetition abilities have been framed within models of psycholinguistic processing, while the motor aspects, which also are critical for task performance, have been largely ignored. We focused our investigation on both the behavioral and speech motor performance characteristics of this task as performed in a learning paradigm by 9‐ and 10‐year‐old children and young adults. Behavioral (percent correct productions) and kinematic (movement duration, lip aperture variability – an index of the consistency of inter‐articulator coordination on repeated trials) measures were obtained in order to investigate the short‐term (Day 1, first five vs. next five trials) and longer‐term (Day 1 vs. Day 2, first five vs. next five trials) changes associated with practice within and between sessions. Overall, as expected, young adults showed higher levels of behavioral accuracy and greater levels of coordinative consistency than the children. Both groups, however, showed a learning effect, such that in general, later Day 1 trials and Day 2 trials were shorter in duration and more consistent in coordination patterns than Day 1 early trials. Phonemic complexity of the nonwords had a profound effect on both the behavioral and speech motor aspects of performance. The children showed marked learning effects on all nonwords that they could produce accurately, while adults’ performance improved only when challenged by the more complex nonword stimuli in the set. The findings point to a critical role for speech motor processes within models of nonword repetition and suggest that young adults, similar to children, show short‐ and longer‐term improvements in coordinative consistency with repeated production of complex nonwords. There is also a clear developmental change in nonword production performance, such that less complex novel sequences elicit changes in speech motor performance in children, but not in adults.     

Developing and Communicating Responsible Data Management Policies to Trainees and Colleagues

The basic components of data management including data ownership, collection, selection, recording, analysis, storage, retention, destruction, and sharing. A number of important principles underlie best practices for each of these components; these include recording details such that another can repeat the experiment, keeping the data safe, managing storage in such a way as to facilitate easy retrieval for the period of time required by regulatory agencies and establishing data sharing principles with colleagues before collaborations begin. Experience as practicing scientists and teachers has aided in developing helpful strategies and approaches for communicating these principles, policies and practices to trainees and colleagues. We recommend didactic instruction focused by discipline, combined with the use of “teachable moments” in a student’s career, as well as teaching principles versus rules, because changing methods of data collection and storage have implications for data management practices.     

Goal attribution to schematic animals: do 6‐month‐olds perceive biological motion as animate?

Infants are sensitive to biological motion, but do they recognize it as animate? As a first step towards answering this question, two experiments investigated whether 6‐month‐olds selectively attribute goals to shapes moving like animals. We habituated infants to a square moving towards one of two targets. When target locations were switched, infants reacted more to movement towards a new goal than a new location – but only if the square moved non‐rigidly and rhythmically, in a schematic version of bio‐mechanical movement older observers describe as animal‐like ( Michotte, 1963 ). Goal attribution was specific to schematic animal motion: It did not occur if the square moved rigidly with the same rhythm as the animate stimulus, or if the square had the same amount of non‐rigid deformation, but in an inanimate configuration. The data would seem to show that perception of schematic animal motion is linked to a system for psychological reasoning from infancy. This in turn suggests that 6‐month‐olds may already interpret biological motion as animate.     

A preliminary study of medial temporal lobe function in youths with a history of caregiver deprivation and emotional neglect

Previous research findings have linked caregiver deprivation and emotional neglect with sensitivity to threatening cues. The present preliminary study investigated whether dysfunctions of the medial temporal lobe could underlie these associations. Using fMRI, we measured medial temporal lobe responses to emotional faces (angry, fearful, happy, neutral) among 30 youths. Eleven of the youths had a history of caregiver deprivation and emotional neglect. Attention states (i.e., attention to anger, fear, or physical attributes, or passive viewing) were systematically manipulated. Relative to comparison youths, youths with a history of caregiver deprivation and emotional neglect showed significantly greater left amygdala and left anterior hippocampus activation during the processing of threatening information. To our knowledge, these findings are the first to demonstrate altered medial temporal lobe function during the processing of threat cues in youths with a history of caregiver deprivation and emotional neglect.     

Development of a fully automated system for delivering odors in an MRI environment

We describe the development and evaluation of a computer-controlled system for delivering odors in a magnetic resonance imaging (MRI) environment. The system allows a timely presentation of different odors in synchrony with MRI sequences and participant’s inspiration phase. The rise/fall time of odor deliverance has been optimized to generate prompt and strong stimulations. Equipped with a user-friendly programming interface, the system can be used reliably in a wide range of experimental paradigms. We have paid particular attention to developing a portable system that is relatively easy, rapid, and inexpensive to replicate. The equipment has been tested in a 3-Tesla MRI in a boxcar paradigm, in which stimulation conditions alternated with rest periods (no stimulation). The experiment demonstrated the good functioning of the device and its efficiency in producing the expected activation in the olfactory cortex; it also revealed some methodological and technical aspects to be improved.
