Linguistic and nonlinguistic auditory processing of rapid vowel formant (F2) modulations in university students with and without developmental dyslexia

To help resolve the issue of whether developmental dyslexia (DD) is related to central auditory processing deficits or to language-specific processing deficits, we had nine dyslectic and nine nondyslectic right-handed undergraduate students perform linguistic (Experiment 1: phoneme identification) and nonlinguistic (Experiment 2: formant rate change detection) tasks. In Experiment 1, subjects listened to synthetic vowels whose second formant (F2) was modulated sinusoidally with F1, F3, and F4 held constant. F2 modulation rate (4-18 Hz) was manipulated within and across stimuli. The groups did not differ in phoneme identification. Experiment 2 was run three times and showed that the control subjects' performance improved across runs whereas the dyslexics' deteriorated across runs (p < .0001), suggesting practice and fatigue effects, respectively. Performance on the two experiments correlated significantly and negatively for the dyslexic subjects only. These results suggest that resource depletion or frontal lobe dysfunction may be implicated in developmental dyslexia.

Promoting Attachment and Mentalization for Parents and Young Children in the Foster Care System: Implementing a New Training and Treatment Approach in an Agency

The Building Blocks Program is an innovative psychodynamic treatment approach that was designed to fit within a social service agency structure. It is based on concepts of attachment, attunement, and mentalization and builds on the research of Beatrice Beebe (2003), Peter Fonagy and colleagues (2002), Arietta Slade (2005), Howard and Miriam Steele (2008), and Dan Stern (1985). The Building Blocks Program targets birth mothers and their young children under age 5 who have been or are in danger of being removed from their families. In the beginning of the program, the Building Blocks therapists faced many challenges. As noted (Remez, this issue), many of the therapists were unfamiliar with a Reflective Supervision model of learning. They were accustomed to a more traditional pedagogical approach that emphasized critiquing their work, with a focus on their clients’ pathology. The Building Blocks model focuses on therapist and client safety and support, prompting a paradigm shift in the therapists’ thinking about supervision and how to conduct therapy.     

Demonstrations of a generation effect in context memory

Generation often leads to increased memorability within a laboratory context (see, e.g., Slamecka & Graf, 1978). Of interest in the present study is whether the benefits of generation extend beyond item memory to context memory. To investigate this question, in three experiments, we asked subjects to remember in which of two contexts they had read or generated words. In Experiment 1, the contexts were two different rooms; in Experiment 2A, the contexts were two different computer screens; in Experiment 2B, the contexts were different perceptual characteristics of the to-be-remembered words. In all experiments, subjects were better at remembering the context of generated words than of read words.     

Initial resource assembly in new ventures: does location matter?

The formation of a new venture requires crucial choices that impact the future success of the firm. An important initial decision is whether or not to start the new venture from home or from a separate location. In this paper, we examine the impact of firm-location decisions on the resource assembly process. Resource assembly is the first step taken by entrepreneurs to begin building a resource base, and it involves gaining ownership or control over resources. Our findings indicate that resource profiles significantly differ by location. In addition, away-based businesses assemble significantly higher counts of physical, financial, and organizational resources.     

Gender differences in implicit and explicit memory for affective passages

Thirty-two participants were administered 4 verbal tasks, an Implicit Affective Task, an Implicit Neutral Task, an Explicit Affective Task, and an Explicit Neutral Task. For the Implicit Tasks, participants were timed while reading passages aloud as quickly as possible, but not so quickly that they did not understand. A target verbal passage was repeated three times, and alternated with other previously unread passages. The Implicit Affective and Neutral passages had strong affective or neutral content, respectively. The Explicit Tasks were administered at the end of testing, and consisted of multiple choice questions regarding the passages. Priming effects in terms of more rapid reading speed for the target compared to non-target passages were seen for both the Implicit Affective Task and the Implicit Neutral Task. Overall reading speed was faster for the passages with neutral compared to affective content, consistent with studies of the emotional Stroop effect. For the Explicit memory tasks, overall performance was better on the items from the repeated passage, and on the Affective compared to Neutral Task. The male subjects showed greater priming for affective material than female subjects, and a greater gain than female subjects in explicit memory for affective compared to neutral material.
