A review of the tip-of-the-tongue experience

The tip-of-the-tongue experience (TOT) has intrigued psychologists for nearly a century. R. Brown and McNeil (1966) provided the first systematic exploration of the phenomenon, and the findings since their seminal study suggest that TOTs (a) are a nearly universal experience, (b) occur about once a week, (c) increase with age, (d) are frequently elicited by proper names, (e) often enable access to the target word's first letter, (f) are often accompanied by words related to the target, and (g) are resolved during the experience about half of the time. Important questions remain concerning TOTs: (a) Are emotional reactions necessary, (b) do only low frequency targets elicit TOTs, (c) do TOTs reflect incomplete target word activation or interference from related words, and (d) do spontaneous retrievals really occur? A more precise definition of the TOT experience is needed, as well as greater uniformity in the information gathered during TOTs.     

Reducing the effects of adjacent distractors by narrowing attention.

Three experiments explored the gradual narrowing of visual attention to a letter target when other letters were positioned close by. The method by which attention was narrowed involved presenting a digit target immediately prior to the latter target and in the same location for progressively shorter durations and requiring the subject to identify both the digit target and the letter target before responding. The response time data from the first 2 experiments indicated that shorter durations of the digit reduced the amount of information processed from noise letters positioned on either side of the letter target. In the third experiment, in which separation of letters was increased slightly, the response times indicated that the information from flanking noise letters may have been virtually eliminated.     

Incidental memory for format of presentation of number stimuli: Evidence from monolinguals and bilinguals

Are numerical stimuli represented in an abstract code or is information about surface format preserved in memory? Three experiments bearing on this issue are reported. All used an incidental recall procedure. Two experiments examined memory for numeral versus word format in monolinguals and the third examined memory for words in the first versus second language of Spanish-English bilinguals. Across all studies, memory for format of number presentation was above chance and was as high as 76% under certain conditions. Implications for number representation are discussed.     

Back to basics: Percentage agreement measures are adequate, but there are easier ways

Percentage agreement measures of interobserver agreement or "reliability" have traditionally been used to summarize observer agreement from studies using interval recording, time-sampling, and trial-scoring data collection procedures. Recent articles disagree on whether to continue using these percentage agreement measures, and on which ones to use, and what to do about chance agreements if their use is continued. Much of the disagreement derives from the need to be reasonably certain we do not accept as evidence of true interobserver agreement those agreement levels which are substantially probable as a result of chance observer agreement. The various percentage agreement measures are shown to be adequate to this task, but easier ways are discussed. Tables are given to permit checking to see if obtained disagreements are unlikely due to chance. Particularly important is the discovery of a simple rule that, when met, makes the tables unnecessary. If reliability checks using 50 or more observation occasions produce 10% or fewer disagreements, for behavior rates from 10% through 90%, the agreement achieved is quite improbably the result of chance agreement.     

Relations among cognitive,semantic, and syntactic variables in children's comprehension of the minimum distance principle: A 2-year developmental study

Theoretical issues regarding cognitive aspects of the semantic interpretation of two syntactic structures were examined. A 2-year study was conducted investigating possible developmental trends in children's sentence-processing strategies. Experimental materials incorporated two levels of role expectations and two levels of syntactic complexity. Subjects were initially 6–10 years old; 12 original subjects from each age group were retested a year later. Exceptional and typical syntactic structures were not of significantly different difficulty either year. Semantic and cognitive complexity, as reflected in the two levels of expectation, was significant both years (p<0.001). Performance improved, over the 12-month period, in all but the 7- to 8-year-old group (p<0.005). Results are discussed with reference to cognitive strategies in sentence processing.This article is based on research reported at the annual meeting of the Northeastern Educational Research Association, Ellenville, New York, October 29–31, 1975.     

Apparatus for collecting voice chronography data

The conversion of speech into on-off pulse patteras representing talk spurts and pauses is a major tool used by psychologists in analyzing interactive communications behavior. We describe a conversion method and a means for interfacing its output with a computer, which allows the collection of large amounts of speech data from one or more sources. The major improvement over prior art is the ability to reject cross talk between neighbor speakers while permitting the detection of simultaneous speech. In the evaluation of the performance of the apparatus, no errors were detected for single-party speaking. Infrequent small errors occurred in the detection and duration of talk spurts and pauses during two- and three-party speaking, but these would probably be acceptable in most applications.     

Reflection-impulsivity in normal and behavior-disordered children

The primary index of reflection- impulsivity is Kagan's Matching Familiar Figures Test (MFF), which yields both a latency and an error score. To evaluate further the construct validity of these measures, both the latency and error scores of 9- and 15-year-old normal and acting-out behavior-disordered children were compared. Young behavior-disordered children were found to be more impulsive than the other groups on the MFF error measure. No differences occurred on the MFF latency measure. This result is consistent with previous findings with normal children in supporting the construct validity of the MFF error score and raising questions about the construct validity of the MFF latency score. Findings were inconsistent with Kagan's assertion that normal children become more reflective with age. The older behavior-disordered children were more reflective on the error measure than the younger behavior-disordered children and had equivalent error scores to both age groups of normals. This finding suggested a lag in the development of reflection in behavior-disordered children.The authors wish to thank Dr. Kenneth C. Molkner for his valuable assistance in obtaining subjects and for his kind support.     

Startbox-goalbox confinement durations as determinants of self-punitive behavior

Two levels of confinement duration (5 or 60 sec) in either startbox or goalbox were factorially combined with presence or absence of shock during extinction of a runway escape response in a self-punitive paradigm under a spaced-trials procedure. All groups were equated for amount and temporal spacing of handling before and after each trial. Shocked rats were more resistant to extinction than nonshocked rats only when startbox confinement was short. When startbox confinement was long, shock facilitated extinction. Long goalbox confinement enhanced running speed for shocked rats, but only in the presence of shock. It was suggested that duration of startbox confinement affects strength of conditioned fear, with long confinement leading to its extinction.
