In slameka and graf's (1978) study, some participants read word pairs, while other participants had to fill in theblank letters of the second word in a pair with a word related to the first word. the latter group performed better ona later memory task, illustrating thea. spacing effect. b.generation effect. c.cued recall effect. d.multiple trace hypothesis.

The correct answer is b generation effect

Explanation:

It is the name of the research Generation effect (delineation of a phenomena) that was done by Norman Slamecka and Peter Graf in the University of Toronto, Toronto Canada. It was tested on 24 volunteer students of introductory physiology in which each student was given 100 items separated by cards each card presented a word and the initial letter of the response  e. g. (rapid-f). The participants were given five rules 1. Associate (lamp-light) 2. Category (Ruby-diamond) 3. Opposite (Long- short) 4. Synonym (sea-ocean) 5. Rhyme (save-cave), the students were given blocks of 20 cards with a new rule each time. Then 12 of the participants were tested again later and the results do not pointed significantly to the generation effect in the third experimentation with 24 participants divided this way 12(informed participants) and 12 (uninformed participants) The results had a clear cut and pointed to the generation effect. After five experiments there was established the existence of the phenomena in which when a word was generated in the presence of a stimulus and an encoding rule it was better remembered than when the same word was simply read under those conditions (Slamecka & Graf 1978).

disorders of the brain include both behavior disorders and other psychiatric illnesses. the primary difference between a behavior disorder and another type of psychiatric disorder is the presence of choice. psychiatric conditions are considered to be involuntary while in behavior disorders, choices are essential.
