This study examined the relationship between handedness and brain activation in visual cortex areas during letter and shape recognition tasks. Ten right-handed subjects underwent fMRI scanning while performing visual tasks. Regions of interest in left and right fusiform gyri were analyzed. Results showed stronger correlations between handedness scores and activity in left visual areas for letters compared to shapes, supporting the hypothesis that handedness relates more to letter recognition lateralization. This suggests handwriting experience influences visual cortex specialization and neural efficiency during development.

A PROCEDURE FOR IDENTIFYING PRECURSORS TO

We describe a procedure for differentiating among potential precursor responses for use in a
functional analysis. Conditional probability analysis of descriptive assessment data identified
three potential precursors. Results from the indirect assessment corresponded with those
obtained from the descriptive assessment. The top-ranked response identified as a precursor
according to the indirect assessment had the strongest relation according to the probability
analysis. When contingencies were arranged for the precursor in a functional analysis, the same
function was identified as for target behavior, supporting the utility of indirect and descriptive
methods to identify precursor behavior empirically.
DESCRIPTORS: descriptive assessment, functional analysis, precursors, problem behavior,
response-class hierarchies
_______________________________________________________________________________
Functional analysis (Iwata, Dorsey, Slifer,
Bauman, & Richman, 1982/1994) involves
manipulating antecedents and consequences
for the target behavior of interest. Because a
functional analysis requires the repeated occur-
rence of a target response, it may not be
appropriate for response topographies that pose
risk of harm to others (e.g., severe aggression) or
the client (e.g., self-injury). One modification
that has addressed this concern involves a
functional analysis of precursor behavior (i.e.,
arranging contingencies for responses that
reliably precede the target behavior) based on
previous research showing that response topog-
raphies that occur in close temporal proximity
are often members of the same response class,
and by providing differential reinforcement for
earlier responses in the response-class hierarchy,
later more severe responses occur less often
(Harding et al., 2001; Lalli, Mace, Wohn, &
Livezey, 1995; Richman, Wacker, Asmus,
Casey, & Andelman, 1999).
Smith and Churchill (2002) conducted a
functional analysis of precursor behavior and
found similar outcomes from a functional
analysis of the target behavior and a functional
analysis of the hypothesized precursor behavior.
A study by Najdowski, Wallace, Ellsworth,
MacAleese, and Cleveland (2008) extended this
work by demonstrating that an intervention
based on a functional analysis of precursor
behavior was effective in eliminating partici-
pants’ precursor behavior. The implication of
these findings is that outcomes from functional
analyses of precursor responses may be used to
infer the function of more severe topographies
that occur later in the response-class hierarchy.
A potential limitation associated with both of
these studies is that indirect assessments alone
were used to identify precursor responses. Such
assessments have sometimes been found to have
poor reliab.

Neuroimaging technology such as the functional magnetic resonance imaging (fMRI) and the diffusion tensor imaging (DTI) helped to reveal the phonological, semantic, and sentence clusters of the brain's language distribution networks. Technological advances in computer imaging software revealed areas where there were differences in blood oxygen level-dependent (BOLD) signal activation in response to either external and internal stimuli such as light or thinking respectively. Researchers are able to perform whole brain analysis to locate activation or deactivation, or microstructural connectivity strength, tissue alteration, or anatomical impairment.

The third stage of information processing is retrieval. What is the role of retrieval in memory? The retrieval of stored information means locationg it and returning it to consciousness. With well-known information such as our names and occupations, retrieval is effortless and rapid. But when we are trying to remember large amounts of information, or information that is not perfectly understood, retrieval can be difficult or worse-- fail. To retrieve information, you must effectively encode and store the information first; otherwise, you will not be able to recall it.
If, in the "Try it!" box you recalled the list of letters-- good for you; you encoded and stored it effectively. Now, what if you were not able to remember the list of ten letters? What may have gone wrong? In terms of the three processes of memory, it oculd be that you had (1) not encoded the list in a useful way, (2) not entered the encoded information into storage, or (3) stored the information but forgotten the cues for remembering it--such as the abbreviations with in it. (e.g. ECMP).

BRIEF REPORT
Retrieval-Induced Forgetting in Old and Very Old Age
Alp Aslan and Karl-Heinz T. Bäuml

Selectively retrieving a subset of previously studied information can cause forgetting of related,
nonretrieved information. Such retrieval-induced forgetting (RIF) has typically been attributed to
inhibitory control processes. Examining participants with a mean age of ...
Investigating the Functional Utility of the Left Parietal ERP Old/New Effect:...
A success story within neuroimaging has been the discovery of distinct neural correlates of episodic retrieval, providing insight into the processes that support memory for past life events. Here we focus on one commonly reported neural correlate, the left parietal old/new effect, a positive going modulation seen in event-related potential (ERP) data that is widely considered to index episodic recollection. Substantial evidence links changes in the size of the left parietal effect to changes in remembering, but the precise functional utility of the effect remains unclear. Here, using forced choice recognition of verbal stimuli, we present a novel population level test of the hypothesis that the magnitude of the left parietal effect correlates with memory performance. We recorded ERPs during old/new recognition, source accuracy and Remember/Know/Guess tasks in two large samples of healthy young adults, and successfully replicated existing within participant modulations of the magnitude of the left parietal effect with recollection. Critically, however, both datasets also show that across participants the magnitude of the left parietal effect does not correlate with behavioral measures of memory – including both subjective and objective estimates of recollection. We conclude that in these tasks, and across this healthy young adult population, the generators of the left parietal ERP effect do not index performance as expected. Taken together, these novel findings provide important constraints on the functional interpretation of the left parietal effect, suggesting that between group differences in the magnitude of old/new effects cannot always safely be used to infer differences in recollection.

The Effect of Presence and Type of Encoding Cue on Memory-Erica Starr
Hofstra University Cognitive Psychology research seminar (Psy 190) - Erica Starr - Dec. '12 Final Research Paper
Structure and function of the left temporal lobe
The Structure and Function of the Left Temporal Lobe
The temporal lobe is made up of the superior temporal gyrus (STG), middle temporal gyrus (MTG), and the inferior temporal gyrus (ITG). The auditory center (BA 41/42) is located in the anterior STG and the Wernicke’s area (BA 22) is located in the posterior STG. Both the pSTG and pMTG are activated by phonemic discrimination and are involved with processing speech and language. Verbal information is integrated along the superior temporal gyrus. The auditory center and the pSTG are involved with phonological processing and semantics. Sentence comprehension begins in the auditory center and the posterior superior temporal sulcus (pSTS). Semantics continues in the angular gyrus which is located in the inferior parietal lobe. Decreased activation along the left STG negatively affects reading skills.
The left MTG is structurally and functionality connected to the primary language processing regions through the ventral and semantic language pathways. The left MTG stores verbal knowledge and obtains semantic information from the sound-to-meaning network which courses through the MTG. Visual and auditory decoding activate the left MTG. Functional connectivity between the left MTG and the frontal lobe is quite significant. The left MTG share connectivity between the precentral, middle frontal, dorsomedial, and ventromedial cortices, along with the inferior frontal gyri. The left MTG is also significantly connected to the right MTG, inferior occipital gyri and angular gyri bilaterally, and to the limbic system’s posterior cingulate gyri.
The fusiform gyrus is located on the underside of the left inferior temporal gyrus. It engages the adjacent occipital gyrus to form the visual word form area. The VWFA is a critical component of the mature reading and writing network. There are phonological and semantic clusters located in posterior IFG which is responsible for grapheme-phonemic conversion and audiovisual integration of syllables. The posterior temporal lobe and adjacent occipital gyrus is referred to as the occipitotemporal region (OTR). The OTR is critically important to visual and auditory language processing. Damage to the left inferior temporal lobe is associated with visual anomia, an inability to name visual objects.

Bilingualism is beneficial in development of cognitive function in children. The benefits are not limited to improvements in social communication skills, sensitivity to language structures, details, grammar, conflict solving, creativity, analogical reasoning, classification, cognitive flexibility, inhibition and dementia prevention. However, bilingualism effect on cognitive processing of syntactic and semantic violations is not well understood yet. This study aimed to determine the effect of bilingualism on event related potentials (ERP) during semantic and syntactic violation tasks in children and adolescents.
