The house-tree-person test (HTP) is a projective personality test. In the HTP, the test taker is asked to draw houses, trees, and persons, and these drawings provide a measure of self-perceptions and attitudes. It qualitatively assesses a persons’ personality. For example, a very small house might indicate rejection of one's home life. A tree that has a slender trunk but has large expansive branches might indicate a need for satisfaction. A drawing of a person that has a lot of detail in the face might indicate a need to present oneself in an acceptable social light. In the house drawing, the roof might represent one's intellectual side, the walls might represent the test taker's degree of ego strength, and the doors and windows might represent the individual's relation to the outside world. In the tree drawing, the branches might indicate the test taker's relation to the outside world and the trunk might indicate inner strength.However, there is some evidence that the HTP can differentiate people with specific types of brain damage. More specifically, it has been shown to be effective when looking at the brain damage present in schizophrenic patients.

SCORING THE ISB

The Use of the Scoring Examples

Sentence completions are scored from examples in the scoring manuals by assigning a numerical weight from to 6 for each sentence and totaling the weights to obtain the over-all score.
Scoring Principles
1. Omission responses
Omission responses are designated as those for which no answer is given or for which the thought is incomplete. Omissions and fragments are not scored.
It might be thought that omission responses are representative of psychological blocks and, therefore, maladjustments. This seems to be true in some cases.
However, it has been found that such an hypothesis is not tenable in the majority of instances. This conclusion was reached by the authors, as well as by Rotter and Willerman, after study showed that omission responses appear as often in the records for adjusted subjects as for the maladjusted.
It is recognized that in a clinical situation omissions are occasionally pro- vocative since they may point to areas of conflict which the individual does not recognize or cannot bring himself to express. In cases such as these they are, of course, worthy of further exploration. For example, the paper may have frequent references to the mother as a "very wonderful person" and no response given to the stimulus, "My father
Conflict responses
"C," or conflict, responses are those indicating an unhealthy or maladjusted frame of mind. These include hostility reactions, pessimism, symptom elicita- tion, hopelessness and suicidal wishes, statements of unhappy experiences, and indications of past maladjustment. Examples of these types of reactions follow.
"I hate . . . almost everyone." "People . . . destroy what they build." "I suffer . . . from dizzy spells." "Sometimes ... I wonder what's the use." "I wish ... I were dead." "When I was a child ... I spent most of my time in a hospital bed." "In high school ... I was extremely self-conscious and backward." Some conflictive responses have been elicited by stimuli which presuppose a negative reply, but there is a large group of "C" responses which consists of twisted answers. In reply to the stimulus "I like . . . ," the completion may be, "to be alone." Other examples of twisting are: "The happiest time . . . ends badly." "The best . . . years of my life are wasted."
Positive responses
"P," or positive, responses are those indicating a healthy or hopeful frame of mind. These are evidenced by humorous or flippant remarks, optimistic responses, and acceptance reactions. Examples are as follows: "What annoys me . . . are people who squeeze the toothpaste tube in the middle." "The best ... is yet to come." "People . . . are fun."
Here, too, one finds twisted responses, but in this category fall those in which the stimuli suggest a negative reply and the response given is a positive one. For example, such a response made to "I can't . . ." is "be two places at one time." Further examples of the twisted responses are: "I suffer . . . from cold ears on mornings such as today." "The only trouble ... is that there are not more hours in the day."
