Profiling Marital Satisfaction among Graduate Students: an Analysis of the Perceptions of Masters and Doctoral-Students

This study investigated marital satisfaction among graduate students. Using the Marital Satisfaction Inventory-R (MSI-R), 65 graduate students were surveyed. The results revealed multiple common areas of marital concern based on degree program of the student. These findings offer implications for psycho-educational and responsive interventions for clinicians working with this population.     

ACADEMIC HARASSMENT

Although much has been written concerning the sexual harassment of university students, no research has yet directly examined the behaviors of university professors themselves. The present study describes the responses of 235 male faculty members of a prestigious, research-oriented university who responded to a survey inquiring about social and sexual interaction among faculty and students. Although the majority of the responses focused on mentoring and social interactions, a sizable minority (26%) reported sexual involvement with women students. In addition to item frequencies, a structural analysis of the phenomenon of academic harassment is presented, and discussed in the context of the subjects' responses to an open-ended invitation to comment on the study.     

An analysis of item gains and losses in retroactive interference.

The repeated-testing paradigm is used to study both retroactive interference and hypermnesia (the improvement in memory across repeated tests). Considerable theoretical progress has been made by separately analyzing the 2 components of hypermnesia: the recovery of previously unrecalled items on later tests (item gains) and the forgetting of previously recalled items on later tests (item losses). Item gains increase with increases in item-specific processing, whereas item losses decrease with increases in relational processing. The authors suggest that separate analysis of item gains and losses in retroactive interference research may also prove fruitful. Three experiments showed that an interpolated list affects item gains but not losses, whereas processing similarity between the target and interpolated lists affects losses but not gains. These results are interpreted within the relational-item-specific processing framework.     

Single-item memory, associative memory, and the human hippocampus

We tested recognition memory for items and associations in memory-impaired patients with bilateral lesions thought to be limited to the hippocampal region. In Experiment 1 (Combined memory test), participants studied words and then took a memory test in which studied words, new words, studied word pairs, and recombined word pairs were presented in a mixed order. In Experiment 2 (Separated memory test), participants studied single words and then took a memory test involving studied word and new words. In a separate test, they studied word pairs and then took a memory test involving studied word pairs and recombined word pairs. In both experiments, patients were impaired at memory for single items as well as memory for associations, suggesting that the hippocampus is important for both of these memory functions. In Experiment 1, patients appeared to be more impaired at associative memory than item memory. In Experiment 2, patients were similarly impaired at associative memory and item memory. These different findings are considered, including the fact that in Experiment 1 the results depended on the fact that controls produced unexpectedly low false-alarm rates to recombined pairs. We discuss single-item and associative memory from the perspective that the hippocampus and adjacent cortex work cooperatively to signal recognition and that simple dichotomies do not adequately describe the division of labor within the medial temporal lobe.     

The anatomy of amnesia: neurohistological analysis of three new cases

The most useful information about the anatomy of human memory comes from cases where there has been extensive neuropsychological testing followed by detailed post-mortem neurohistological analysis. To our knowledge, only eight such cases have been reported (four with medial temporal lobe damage and four with diencephalic damage). Here we present neuropsychological and post-mortem neurohistological findings for one patient (NC) with bilateral damage to the medial temporal lobe and two patients (MG, PN) with diencephalic damage due to bilateral thalamic infarction and Korsakoff's syndrome, respectively. All three patients exhibited a similar phenotype of amnesia with markedly impaired declarative memory (anterograde and retrograde) but normal performance on tests of nondeclarative memory (e.g., priming and adaptation-level effects) as well as on tests of other cognitive functions. Patient NC had damage to the hippocampus (dentate gyrus and the CA1 and CA3 fields) and layer III of the entorhinal cortex, but with relative sparing of the CA2 field and the subiculum. Patient MG had damage to the internal medullary lamina and mediodorsal thalamic nuclei. Patient PN had damage to the mammillary nuclei, mammillothalamic tracts, and the anterior thalamic nuclei. These findings illuminate several issues regarding the relation between diencephalic and medial temporal lobe amnesia, the status of recognition memory in amnesia, and the neuroanatomy of memory.     

Monitoring syllable boundaries during speech production

This study investigated the encoding of syllable boundary information during speech production in Dutch. Based on Levelt's model of phonological encoding, we hypothesized segments and syllable boundaries to be encoded in an incremental way. In a self-monitoring experiment, decisions about the syllable affiliation (first or second syllable) of a pre-specified consonant, which was the third phoneme in a word, were required (e.g., ka.No 'canoe' vs. kaN.sel 'pulpit'; capital letters indicate pivotal consonants, dots mark syllable boundaries). First syllable responses were faster than second syllable responses, indicating the incremental nature of segmental encoding and syllabification during speech production planning. The results of the experiment are discussed in the context of Levelt's model of phonological encoding.     

Cross-validation of the MMPI-2 in detecting malingered posttraumatic stress disorder

We attempted to cross-validate findings from a previous study (Elhai, Gold, Sellers, & Dorfman, in press) using a clinical sample of combat-related war veterans to distinguish genuine from malingered posttraumatic stress disorder (PTSD) on the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). The MMPI-2 scores of 124 male combat war veterans at the PTSD outpatient treatment program of a Veterans Affairs Medical Center were compared with those of 84 adult college students instructed and trained to malinger PTSD. MMPI-2 overreporting variables examined were F, F-Fb, F-K, F(p), Ds2, O-S, OT, and FBS. A stepwise discriminant analysis identified F. F-Fb, F-K, Ds2, O-S, and OT as the best malingering predictors. A predictive discriminant analysis yielded good hit rates for the model with impressive cross-validation results. We assessed cutting scores for the predictors of the model. We discuss clinical implications for using the MMPI-2 to distinguish malingered PTSD from combat-related PTSD.     

The Psychodynamics of the Patient's Active Episodes

The phenomenon of the patient as active change agent is a critically important, but new and understudied one. This paper attempts to explore and to illustrate with clinical examples the psychodynamic foundations of the patient's activity. The concept of an active episode on the part of the patient is introduced and defined. The paper illustrates the ways that active episodes of self-change on the part of the patient can determine the outcome of psychoanalytic therapy.     

Epinephrine fails to enhance performance of food-deprived rats on a delayed spontaneous alternation task

Increases in blood glucose levels after epinephrine injection appear to contribute to the hormone's effects on learning and memory. The present experiment evaluated whether epinephrine-induced enhancement of spontaneous alternation performance would be attenuated in fasted rats that had blunted increases in circulating glucose levels after injections of epinephrine. Rats deprived of food for 24 h prior to injection of epinephrine exhibited significant attenuation of the increase in blood glucose levels seen in fed rats. When the rats were tested on a delayed spontaneous alternation task, epinephrine enhanced performance in fed rats but not in rats deprived of food for 24 h. These findings are consistent with the view that hyperglycemia subsequent to epinephrine injections contributes to the memory-enhancing effects of epinephrine.
